/*
 * TimeZoneMeet design tokens.
 *
 * One canonical place for color, type, spacing, radius, and shadow.
 * Pages should reference --tzm-* variables instead of hardcoding hex
 * values so the next refresh — or a theme flip — is one diff, not N.
 *
 * House style (shared with scorifya.com):
 *   - Warm palette: ink (near-black) text on paper (warm cream), with an
 *     ember (#e85d2c) orange accent that holds on both light and dark.
 *   - Light/dark via a token swap: :root is light, html.dark re-points the
 *     same semantic tokens. Everything downstream is expressed against
 *     --ink / --paper / --ember etc., so one class flip reflows the site.
 *   - Type: Syne (display/headings) + Sora (body), self-hosted woff2.
 *
 * Semantic primitives that SWAP between themes:
 *   --ink     text / strong foreground
 *   --paper   page background
 *   --mist    muted surface / hairline base
 *   --deep    inverted surface accent
 *   --forest  secondary green (success-ish brand green)
 *   --ember   accent — IDENTICAL in both themes (legible on each bg)
