   design language: Interactive Warmth* Warmth:** Warmth: uses ember hover states; IntersectionObserver with a threshold of 0.15 to trigger reveals creates a gentler and more purpose-built entrance rhythm. Interstitial Bands* Bands:** Bands: Between major content sections, Playfair Display numerals appear at oversized scale (clamp(4rem). "Playfair Display" (Google Fonts) carries Playfair's elegance without competing. Color: warm gray-lavender (#b8a8b0. "Space Mono" (Google Fonts) grounds the marginalia.
