/* Portfolio, blog, posts and 404 — the same "warm" mood as the company top
   (lp-anatomy §7-2, modelled on Bikkuri Donkey), so the whole site reads as one.
   - Paper A #f4efe8 and craft paper #eadfd1 alternate, with oval edges between them.
     White is for cards and the header band only.
   - Colour comes from the logo only: orange, sky, navy. The SVG drawings (rendered at
     build time from src/illustrations.tsx) use the same three.
   - Text and shadows are burnt brown, never black or grey.
   - Fredoka for Latin, numbers and dates; Zen Maru Gothic for Japanese (subset per page).
   - Motion: rows slide 10px and drawings wobble ±3° on hover, reveal once, the stack band
     drifts. All of it sits inside prefers-reduced-motion: no-preference, and site.js skips
     it on Save-Data. Easing is cubic-bezier(.19,1,.22,1). */
