   reiwa.boo — a haunted garden at dusk
   Fairycore × Reiwa-era Japanese sensibility
   Palette: Moon Mist, Twilight Plum, Mist Violet, Spirit Lavender,
   Blossom Pink, Phantom Mint, Dusk Veil, Lantern Glow

   Implementation notes (per DESIGN.md):
   - Mist parallax: implemented via scroll event listener.
     The mist layers sit between content z-index layers.
     (Intersection Observer is also used for card reveal.)
   - Spirit orbs: CSS keyframe animations (driftUp / driftDown).
   - Typography: Cormorant Infant, Quicksand, Caveat (Google Fonts).
     Inter is included as a body-font fallback.
