/* ── Pixel City company site ───────────────────────────────────────────────
   Every page on this site, no build step.

   WHITE PAPER, NEON INK. The ground is #ffffff — the logo stage the brand
   already uses (apps/tsunami/.artifacts/pixel-city-trailer.md, 2026-09-12) —
   and the only two accents are the mark's own violet #7c4dff and coral #ff5a6e.
   The old product site's indigo does not appear here on purpose.

   THE NAMES ARE THE APP'S NAMES. `--bg`, `--bg-card`, `--text`, `--border` and
   the radius scale are the Pixel City design tokens from
   packages/ui/src/tokens.css, so someone arriving from Luma World does not have
   to learn a second vocabulary to change a colour here. The VALUES are this
   site's light palette rather than the app's dark one, which is what a token
   name is for. See .claude/skills/pc-panel-ui.

   ONE THING IS DELIBERATELY NOT TAKEN. The app's `--accent` is sage green
   #5c9a7d. It does not appear here. The accent is the mark's violet → coral,
   because the mark is what a visitor is looking at.

   Coral is a SHAPE colour, never a text colour: #ff5a6e on white is 3.0:1 and
   fails AA. Violet at 4.8:1 passes, and carries the eyebrows.

   OLD NAMES, STILL HERE. `--ink`, `--copy`, `--muted`, `--line`, `--paper` are
   aliases onto the tokens so pages written against them keep working. New rules
   should use the token names.

   This file is the whole shared vocabulary — nav, buttons, hero, bands, cards,
   the product row, the closing CTA, partners, footer. Anything only one page
   uses stays inline in that page.
