# Design Language for chika.bid

## Aesthetics and Tone

chika.bid is **a subterranean auction salon staged inside a 1974 Tokyo basement gallery, photographed off-axis through a rear-view mirror, with every lot illuminated by a single sputtering orange Sodium-vapor street lamp dragged in from outside**. The domain reads two ways at once — *chika* (地下, "below ground" in Japanese) and *bid* (the auction call) — so the site is committed entirely to that double meaning: a **luxury-premium** auction house that is also literally underground, and the visual language is the moment a bid card is held up under that one warm filament and the entire room tilts five degrees because the floor was poured on a slope and nobody ever fixed it.

The aesthetic register is **luxury-premium** (essentially absent from the registry — under 1% if it appears at all in the gold-black-luxury palette token), but reinterpreted *whimsically*, not opulently. This is not Cartier-on-marble luxury. This is **luxury as the basement of a luxury house** — the bonded warehouse where the *real* lots are kept, where the wood floor smells faintly of camphor, where the carpet is too thick by half a centimeter, where the walls are upholstered in burnt-orange linen the color of a cigarette ember held against velvet, and where the auctioneer is a 23-year-old in a wool waistcoat who keeps misreading the catalog and laughing about it. The tone token is **whimsical-creative** (8% of corpus): the site is *playful with its own gravity*. It takes itself seriously enough to commit to the chamfered ash-veneer paneling, the brass corner brackets, and the millimeter-perfect typographic spacing of a real Sotheby's evening-sale catalog — and then it tilts the entire scene 3.7 degrees off true, makes the catalog numbers count *down* instead of up, and lets the lot photographs glow from inside as if every object were quietly radioactive.

The mood is **late, warm, and slightly conspiratorial** — the auction has been running for six hours, three of the lots have been withdrawn for reasons the catalog will not say, the buyers in the front row know each other and nobody else does, and the only light source warm enough to read by is the one orange lamp. There is no daylight in this design. There is no white. There is no cool tone anywhere on the page. Everything that would normally be "white space" is instead the color of unbleached pongee silk under tungsten, and everything that would normally be black is the color of a darkroom safelight at the moment it is switched on.

The visitor's affective experience should be: *I am not supposed to be in here, but the man at the door waved me through, and now I am holding a numbered paddle made of pearwood, and I cannot tell if the chandelier is glowing or if I am.*

## Layout Motifs and Structure

The dominant structural commitment is **masonry** (8% of corpus — actively underused, deliberately claimed as the spine), but executed as a **hand-set printer's chase, not a Pinterest grid**. The page is built as if a Tokyo specialty letterpress shop in 1974 had to typeset an evening-sale auction catalog by locking lead slugs and zinc plates into a cast-iron frame. The masonry is therefore *physical and asymmetric*, with column widths that do not divide evenly, with lots that are deliberately sized in non-grid increments (a 3:5 silk-screen rectangle next to a 2:3 ambrotype next to a square netsuke plate), and with negative gutters where the chase has been rammed too tight and the slugs are touching.

**Grid spec — the chase.**
- Reference frame: 1440 × 1024 desktop, 820 × 1180 tablet, 390 × 870 mobile.
- The entire page is held inside a `--chase-frame`: a 1.5px solid border-line at `#3A1F0E` (oxidized iron), with hand-mitered corners drawn as four separate `<svg>` corner glyphs (each a 24×24 brass bracket with three rivets).
- Inside the chase: a **non-uniform 11-column substrate**. Column widths in pixels at 1440 desktop: `108, 88, 132, 96, 144, 88, 116, 100, 152, 96, 124` — these are deliberately *not* fibonacci, *not* golden-ratio, and *not* equal. They are the actual em-widths of eleven lead slugs salvaged from the printer's drawer. Gutters are 12px between columns, except between columns 4-5 and 8-9, where the gutter collapses to 0 (the slugs are touching).
- Row pattern: rows are 88px on the *quoin baseline* but lots may consume 1, 2, 3, 4, or 7 rows tall — never 5 or 6. (The number 5 is reserved for *lot reservations*; the number 6 is considered unlucky in this fictional house.)
- Lots placed via CSS Grid `grid-row` and `grid-column` spans, hand-keyed, no auto-flow. The page is a *composition*, not a feed. There are exactly **23 lots** on the index page — the 23 evening-sale lots of the Inoue Estate Sale, March 14 1974.

**The 3.7-degree tilt.** The entire chase frame is rotated `transform: rotate(-3.7deg)` and then *counter-rotated* on its child content `transform: rotate(3.7deg)`, so that the *frame* tilts but each *lot card* sits true on its own axis. This is the **tilt-3d** seed (14% — used here at the chassis level rather than the per-card hover level, which is the standard reading). On hover, individual lot cards perform an additional `rotateX(6deg) rotateY(-4deg)` parallax-on-cursor-axis tilt, but the hover is not the primary tilt — the primary tilt is the static, all-the-time tilt of the room itself.

**Sectional structure of the long-scroll.**
- **Foyer** (first 100vh): a single full-bleed plate of the auction room photographed through the mirror, plus the house mark and the words `CHIKA · BID · ESTATE SALE No. 0146 · MARCH 14 1974` set on a tilted axis.
- **Catalog Index** (the masonry chase, ~600vh of scroll): the 23 lots, each a `<figure>` with hand-set caption.
- **Provenance Hall** (160vh): a vertical timeline of the Inoue family from 1894 to 1974, set as a single-column letter-press strip down the page center.
- **Reading Room** (140vh): three long-form essays on the lots, set in 11-pica columns with deep paragraph indents.
- **Bid Desk** (80vh): the silent bid form, treated as a deposit slip from the Bank of Tokyo, 1974 dating.
- **Kolophon / Colophon** (60vh): hand-set credits, paper stock, ink mix, the name of the (fictional) house printer.

There is **no sticky navigation, no sidebar, no breadcrumbs, no progress indicator**. The visitor scrolls or does not. There is one navigation gesture only: a small brass *paddle number* at top-right that, when clicked, rotates 90 degrees and reveals a ten-link table of contents set in 9px caps, then rotates back when dismissed. This avoids the dashboard (25%), sidebar (27%), and minimal-navigation (6%) clichés simultaneously.

## Typography and Palette

**Typefaces — Google Fonts only, all confirmed available.**

- **`Familjen Grotesk`** (variable, 400–700) — the principal display and running face, serving the **grotesque-neo** seed (3% of corpus). Familjen Grotesk is a 2021 Swedish neo-grotesque with subtly humanist apertures, a slightly tall x-height, and — critically — a *real* italic with cursive descenders, not just an oblique. It reads as 1974 Helvetica from across the room and reads as 2021 contemporary up close, which is exactly the temporal double-exposure this design needs. Used at 13.5/19 for body, 9/12 for catalog metadata, 84/88 for lot numbers, 168/168 for the house mark.
- **`Cormorant Infant`** (regular 400, italic 400) — the catalog-essay running face for the Reading Room. The *Infant* cut of Cormorant has shorter ascenders and rounder bowls than the standard cut, suitable for the slightly-childlike, slightly-conspiratorial tone the essays take. Used at 15/26 with a 0.6em paragraph indent and no inter-paragraph spacing — the classic letterpress run-on paragraph, broken only by a single ornament glyph (¶ or §).
- **`JetBrains Mono`** (regular 400, weight 600 for emphasis) — used *exclusively* for the bid amounts, lot dimensions, and provenance ledger entries. The typewriter-like rendering of monospace numerals against the neo-grotesque surround is the typographic *bid-card-against-the-velvet* gesture. Mono is 95% of the corpus and unavoidable as a token; this design uses it sparingly and *only for ledger data*, not for code or terminal pretense.

**Type composition rules.**
- Lot numbers are set in Familjen Grotesk Medium at 84pt, color `#FF6A1F` (the lamp), aligned to the *baseline* of the first photograph in each card, never to the top.
- Body copy is left-aligned, ragged-right, hyphenated only at hand-set break points (which are pre-encoded as `&shy;` in the source — there are exactly 47 hand-set break points across the index page).
- Italic in Familjen Grotesk is used *only* for: lot names in foreign languages, the names of withdrawn-from-sale lots, and the auctioneer's interjections (set inline with em-dashes as if she had spoken aside to the floor).
- Small caps are used for buyer-paddle ranges and provenance markers; tracking is set to 0.16em.
- Numerical tabular figures are enabled globally via `font-feature-settings: 'tnum' on, 'lnum' on` for Familjen Grotesk; the lot prices line up vertically across the whole catalog.

**Palette — burnt-orange (1% of corpus, deliberately the load-bearing token).**

| Token             | Hex       | Role                                                     |
|-------------------|-----------|----------------------------------------------------------|
| `--lamp`          | `#FF6A1F` | The single sodium-vapor lamp; lot numbers, accent rules, the glow inside lot photographs |
| `--ember`         | `#C7421A` | Deeper burnt-orange; section dividers, paddle numbers, the chase corner brackets |
| `--ash`           | `#7A2D14` | The wall lining at distance; secondary captions, the tilt-true gridline |
| `--char`          | `#1B0E07` | The room ground; the page background, body text on light cards |
| `--char-soft`     | `#2A1A10` | Softer ground for the second-tier cards; never pure black |
| `--pongee`        | `#E8D9BB` | Unbleached pongee silk; the off-white running ground for body copy under tungsten |
| `--pongee-deep`   | `#C9B391` | The shaded fold of the pongee; card backs, deep gutters |
| `--brass`         | `#9A6F2A` | The corner brackets, the rivets, the paddle hinge |

**Strict rules.**
- **No pure black, no pure white.** The page background is `--char` `#1B0E07`; the lightest surface is `--pongee` `#E8D9BB`. Every other color is interpolated on the burnt-orange / unbleached-silk axis.
- **No blue, no green, no purple anywhere on the page.** Even the link underlines are `--ember`. Even the form-field focus rings are `--lamp`.
- **No CSS gradient longer than 24px.** This explicitly avoids the **gradient** token (96% of corpus). Where a transition is needed (the glow inside a photograph, the fade from `--char` to `--char-soft` at section seams), it is rendered as a 16-step *dither pattern* using a 4×4 Bayer matrix, producing the visual texture of a 1974 newsprint halftone, not a smooth digital gradient.
- **Warm bias is total** — but this is *burnt* warm, the warmth of a thing that has already been on fire and is now cooling, not the warmth of dawn. The corpus is 95% warm; this design narrows that warmth to a single 28-degree wedge of the hue circle, from `#FF6A1F` (lamp) to `#7A2D14` (ash).

## Imagery and Motifs

**Zero photography (98% of corpus — its exclusion is the largest single deviation).** All visual content is hand-composed from SVG, CSS dither, and three small raster textures bound into the bundle.

**Imagery family 1 — Neon-Glow lot plates (the seed: neon-glow, 6% of corpus).** Each of the 23 lots is rendered as a hand-drawn SVG silhouette (the netsuke, the lacquer box, the Hanafuda deck, the bronze incense burner, the kintsugi tea bowl, the woodblock print, the silk scroll, the tortoise-shell hairpin, the mother-of-pearl inlay tray, etc.) — each silhouette filled with a `--char-soft` body and surrounded by a 14px outer-glow halo in `--lamp`, generated via SVG `<filter>` with `feGaussianBlur stdDeviation="6"` plus a `feColorMatrix` that pushes the glow toward `#FF6A1F` and away from any bleed into yellow or red. The neon-glow here is *not* the cyberpunk arcade neon (which is the corpus's standard reading); it is the **filament-glow of a single warm lamp transferring a faint orange aura onto a dark velvet object**. Each lot photograph appears to be *radioactive in burnt-orange*. The glow pulses on a 4.7-second sine cycle (very slow, very subtle, never above 0.18 alpha modulation), staggered by lot-id so that the 23 lots breathe out of phase with each other and the page never has a global rhythm.

**Imagery family 2 — Retro-Patterns chase ornaments (the seed: retro-patterns, 4% of corpus).** The chase frame is decorated with **1974 Showa-era Japanese auction-house ornaments**, hand-drawn as inline SVG: the *kiku* sixteen-petal chrysanthemum dingbat at section heads, the *mitsudomoe* triple-comma at lot-number flags, the *seigaiha* (overlapping-waves) pattern at 12% alpha as the chase background, and a hand-cut *nori* (rule) of alternating long-and-short dashes (4px solid, 2px gap, 1px solid, 2px gap) used as section dividers. These ornaments are deliberately **not the corpus's typical floral-botanical (1%) or geometric-shapes (4%) reading**; they are *house-mark decorative patterns*, the kind a 1974 specialty printer cuts in zinc and re-uses on every catalog cover until the zinc wears out and the dingbats lose their crispness. Each ornament is rendered with a deliberate 1px softening of the SVG path (via `stroke-linejoin: round` and a 0.5px `feGaussianBlur`) to suggest exactly that worn-zinc edge.

**Imagery family 3 — Provenance ledger glyphs.** The Provenance Hall timeline uses small SVG marks: a `kanji-stamped` red square for ownership transfer (drawn as a 14×14 vermilion `--ember` square containing a single hand-traced kanji), a brass keyhole for *sealed and re-sealed*, a small auction gavel for *passed at auction*, a folded letter for *correspondence on record*. Twelve glyphs total, all hand-drawn, all in `--brass` and `--ember`.

**Imagery family 4 — The room.** The Foyer plate is a single 1200×800 SVG composition (no raster) of the auction room: 19 brass-banded chairs in three rows, two side-tables with cataloged lots under cloth, the auctioneer's pulpit at far left, the orange lamp dead center hung on a single hand-drawn cord, and the rear-view mirror at upper-right showing the back of the room. The mirror is *re-staged*, not a literal reflection: it shows what is *behind* the page (the title block, the date, the house mark). This is a quiet trick that should reward a second look.

**Three texture rasters, total budget 41KB.**
- `linen.png` (256×256 tiling, ~12KB) — the burnt-orange wall linen at 8% alpha, applied to all `--char` ground.
- `pongee.png` (256×256 tiling, ~14KB) — the unbleached silk weave at 16% alpha, applied to all `--pongee` ground.
- `bayer.png` (16×16 tiling, ~1KB) — the 4×4 Bayer dither pattern, used at 8% alpha to break up flat color fields and prevent banding.

**No photography. No 3D render. No icon-set. No Lottie. No video. No bokeh-background. No lens-flare. No glassmorphic-cards.** All four corpus-saturated imagery tokens are deliberately refused.

## Prompts for Implementation

Build chika.bid as **one HTML document, one CSS file, one ES module, three texture rasters, and twenty-eight inline SVG fragments emitted from the lot data at build time**. No framework, no bundler, no router, no service worker. Total uncompressed bundle target: under 110KB (including the three textures). The page is a single long scroll. Bias every implementation decision toward **storytelling-as-typography and atmosphere-as-restraint**, never toward conversion-funnel patterns, never toward CTAs, never toward stat-grids, never toward pricing tables.

**Document structure.**

  </main>
</body>
```

**The static tilt.** Apply `transform: rotate(-3.7deg)` to `main.frame` and `transform: rotate(3.7deg)` to each direct child, so the chase frame and the corner brackets are visibly tilted but each section's content sits true. The visual effect: the whole *room* leans, but the *catalog page on the auctioneer's lectern* is straight.

**The masonry chase.** Use `display: grid` with `grid-template-columns: 108px 88px 132px 96px 144px 88px 116px 100px 152px 96px 124px` (sum 1244px, plus 10×12px gutters = 1364px, plus 2×38px chase margins = 1440px). Lot positions are hand-keyed in the HTML via `data-row`, `data-col`, `data-span-r`, `data-span-c` attributes that are read by inline CSS custom properties on each `<figure>`. **No auto-placement.** The composition is fixed and authored, not generated.

**The neon-glow on hover.** Each `.lot-glyph` SVG has a default `filter: url(#glow-rest)` with `stdDeviation="6"` on the inner Gaussian blur. On `:hover` of the parent `.lot`, the filter switches to `#glow-active` with `stdDeviation="14"`, animated via the `filter` interpolation over 320ms with a custom cubic-bezier `(0.34, 1.20, 0.64, 1)` — a slow lift, slight overshoot, soft return. The lot card *also* tilts on hover: `transform: rotateX(6deg) rotateY(-4deg) translateZ(8px)` with `transform-style: preserve-3d` and `perspective: 1400px` set on the `.catalog` parent. This is the **tilt-3d** seed (14% of corpus) executed as an interaction, in addition to the static page-tilt described above.

**The breathing pulse.** A single `@keyframes ember-breathe` animates `--glow-stop-1` from `#FF6A1F` to `#FF7A28` and back over 4.7s ease-in-out infinite. Each lot has its `animation-delay` calculated as `calc(var(--lot-id) * 0.207s)` so the 23 lots breathe out of phase. Disable via `prefers-reduced-motion: reduce` — the glow then sits at its midpoint, static, no animation.

**The paddle TOC.** A single `<nav class="paddle">` element sits at top-right, `position: fixed`, 56px wide × 88px tall, drawn as a brass paddle with the number `0146` engraved on its face. On click, it `transform: rotate(90deg) translateX(-280px)` over 240ms, revealing a 280×600px deep-burnt-orange linen panel with ten anchor links in 9px caps. Clicking outside the panel (or pressing Escape) returns the paddle to its rest position. **No hamburger, no drawer, no overlay scrim** — the paddle *itself* opens.

**Scroll behavior.** The Foyer parallax: the orange-lamp SVG inside the foyer plate has its `transform: translateY(calc(var(--scroll) * -0.3px))` driven by a single `IntersectionObserver` + `requestAnimationFrame` loop. *No* full-page parallax (94% of corpus, refused). *No* scroll-triggered animations on every section (16% of corpus — used here on exactly two elements: the lamp, and the rear-view mirror's reveal of the title in the Foyer). The Provenance Hall, Reading Room, and Bid Desk sections do *not* animate on scroll; they are simply *there* when the reader reaches them.

**The bid form.** The Bid Desk is a single `<form>` styled as a 1974 Bank of Tokyo deposit slip: pongee ground, ember-orange hand-rule lines at 8.5px row pitch, six fields (`Lot Number`, `Bidder Paddle`, `Maximum Bid (¥)`, `Telephone`, `Authorized Signature`, `Date`). Submit is a single brass-stamp button that reads `提出` (submit) and, on click, plays a 240ms ink-stamp animation (a small SVG inkblot scaled from 0 to 1, rotated 7 degrees, then settled). The form does not actually submit anywhere — `onSubmit` runs `e.preventDefault()` and reveals a small handwritten note on the deposit slip that reads *Received. The salon will be in touch by post.* This is whimsical-creative tone executed as form behavior.

**Refusals (explicit).**
- **No CTA buttons** anywhere except the form's brass stamp.
- **No pricing tier blocks, no "compare plans," no stat-grids.** Lot estimates are inline typographic ranges, not boxed.
- **No card-grid** (73% of corpus). The masonry chase is a *composition*, not a feed.
- **No cursor-follow** (73% of corpus). The cursor is a normal cursor. The page does not chase it.
- **No magnetic buttons** (62% of corpus). The bid stamp is heavy and still.
- **No spring/elastic interpolation as the default** (75% / 17%). Motion uses a single hand-tuned cubic-bezier `(0.34, 1.20, 0.64, 1)` for the glow, and `(0.4, 0.0, 0.2, 1)` for the paddle rotation. No spring physics, no elastic overshoot beyond the glow's gentle 1.20.

**Accessibility.** Honor `prefers-reduced-motion` for the glow pulse and the paddle rotation (both fall to static end-states). Honor `prefers-color-scheme` only insofar as: in *light* preference, the page does not change — this is a basement, there is no daylight version, and that is the design. (The colophon notes this politely.)

## Uniqueness Notes

This design's deliberate departures from the 110 designs already in the registry, and from common interpretations of the seed:

1. **Luxury-premium read as the basement of a luxury house, not its showroom.** The luxury-premium aesthetic token is essentially absent from the registry (gold-black-luxury palette is at 0%). When luxury appears in the corpus, it tends toward marble-and-gold opulent-grand. chika.bid commits to the *opposite half of the same vocabulary*: the bonded warehouse, the back-office vault, the wood-panelled basement — luxury as *trade infrastructure*, not as showroom display. The site looks expensive because the room is restrained, not because it is gilded. This is the most significant differentiator: every other luxury-coded design in the corpus reaches for marble-classical (6%) or chrome-metallic (9%); this one reaches for camphor-soaked pongee silk and printed catalogs.

2. **Burnt-orange (1% of corpus) as the load-bearing single hue, not as an accent on warm-gradient.** The corpus uses warm-palette tokens at 95% saturation, but the burnt-orange specific token sits at 1% and is almost always paired with creamy-pastel or sepia-nostalgic into a *gradient*. chika.bid commits to burnt-orange as a *single illuminant* — the entire page is lit by one orange filament, and every surface is the color the filament makes it look. There is no second light source. There is no cool-tone counterpoint. This is the rarest palette commitment a CMassC site has made, and it is held to without exception: zero blue, zero green, zero purple, zero true-black, zero true-white.

3. **Masonry (8%) as a hand-set printer's chase, not as a Pinterest scroll.** Masonry in the corpus is read as a tile-feed: equal-width columns, variable heights, infinite scroll. chika.bid grounds masonry in its *original physical referent* — the cast-iron frame a letterpress printer locks lead slugs into — and that re-grounding produces a *non-uniform, non-equal-column, non-fibonacci* substrate of 11 hand-measured column widths and 23 hand-keyed lot positions. The composition is *authored*, not generated. There is no infinite scroll. There are exactly 23 lots, in a fixed order, never re-flowed.

4. **Tilt-3d (14%) applied at the chassis level, not the per-card hover level.** In the corpus, tilt-3d is almost universally a per-card mouse-parallax interaction. chika.bid uses it twice: once *statically* as a 3.7-degree page-frame tilt (the room itself leans), and once *interactively* as a 6×4-degree per-lot hover tilt. The static tilt is the unusual move — it commits to the fiction that the floor of the auction salon was poured on a slope, and never gives the visitor a "level" reading of the page. This is whimsical-creative tone executed structurally, not decoratively.

5. **Neon-glow (6%) as filament-warmth on velvet, not as cyberpunk arcade lighting.** The corpus's six occurrences of neon-glow are all electric-blue / hot-pink / acid-green arcade neon, the standard cyberpunk reading. chika.bid inverts the affective register entirely: the glow is a single *sodium-vapor warm filament* at 1900K, applied to dark velvet objects, with extremely low alpha modulation (max 0.18) and a very slow 4.7-second breath cycle. The neon is *quiet*. It is the glow of a thing being looked at, not a thing demanding to be looked at. This re-reading of the same imagery token is the design's largest thematic move.

6. **Whimsical-creative tone (8%) committed as gentle, not as zany.** Whimsy in the corpus tends toward bright color, pop-art primitives, hand-drawn squiggles, dopamine-neon. chika.bid commits to whimsy as *understated misbehavior inside a serious frame*: the auctioneer who keeps misreading the catalog, the lot numbers that count down instead of up, the rear-view mirror that shows the title block, the paddle that hinges instead of drawer-slides, the bid form that responds in handwritten Japanese-English. The whimsy is *small and warm*, and it lives entirely inside an otherwise extremely composed and restrained typographic frame. This is whimsy as a quality of *attention*, not as a quality of *form*.

7. **Refusal of seven corpus-saturated patterns, all named.** Photography (98%), gradient (96%), warm-as-broad-spectrum (95%), parallax-everywhere (94%), full-bleed (90%), centered (80%), cursor-follow (73%), spring/stagger as default motion (75%/76%), card-grid feed (73%), and magnetic buttons (62%) are *all* explicitly refused or narrowly redefined. The page has no photography, no smooth gradients (only Bayer-dithered transitions), one warm sub-wedge of 28 degrees, two scroll-triggered elements only, no full-bleed sections (the chase frame is always visible), an asymmetric tilted composition, no cursor effects, no spring physics, no card feed, no magnetic interactions. Each refusal is named in the implementation notes so the build does not drift back toward corpus mean.

8. **Document chosen seed/style:** *aesthetic: luxury-premium, layout: masonry, typography: grotesque-neo, palette: burnt-orange, patterns: tilt-3d, imagery: neon-glow, motifs: retro-patterns, tone: whimsical-creative.* Every one of these seven tokens is at or below 14% in the corpus (luxury-premium effectively 0%, burnt-orange 1%, grotesque-neo 3%, retro-patterns 4%, neon-glow 6%, masonry 8%, whimsical-creative 8%, tilt-3d 14%). The seed is *deliberately rare across all eight axes simultaneously*, and the design holds each token to its underused interpretation rather than reverting to corpus mean.
