/*
  Cruise landing: design system notes (for whoever touches this next).

  Brand: Charcoal #2C2A29 + Amber #E9BA50 (official brand kit, 2026-09-30).
  Source of truth for color is the app itself
  (cruise_flutter/lib/core/theme/app_color_tokens.dart). The values below are
  those tokens verbatim, so real app screenshots blend into the page with no
  seams. One accent only: amber (--primary) for fills, dark amber (--accent)
  for amber text on light. One theme per visitor, no inverted sections: it
  follows prefers-color-scheme until the visitor picks one with the nav's
  theme button, which sets <html data-theme="light|dark"> (see script.js).
  So every dark rule appears twice: under the media query (unless forced
  light) and under [data-theme="dark"]. Keep each pair in sync.

  Logo rules (brand kit): on light, charcoal ink + amber accent; on dark,
  solid amber (--mark-ink / --mark-accent). Clear space around the logo >=
  the gap inside the split-C. Minimum: mark 16px, wordmark 80px wide.

  Shape scale (one rule, used everywhere):
    interactive + chips ........ full pill
    outer shells (bezel) ....... 32px, inner cores 26px (concentric: 32 - 6)
    media inside cores ......... 20px
    small tags ................. 10px

  Type: Vazirmatn for Persian, Montserrat for Latin (both self-hosted, OFL;
  Latin runs are marked lang="en"). Persian script must never get
  letter-spacing (it breaks the joins), so tracking is only applied to the
  Latin CRUISE logotype.

  Motion: transform + opacity only. All of it collapses under
  prefers-reduced-motion. Reveal-on-scroll signals hierarchy; the hero
  entrance signals depth (front phone lands first).

  z-index scale: nav 20, grain 30. Nothing else needs one.

  Blog pages are generated by scripts/build-blog.mjs and reuse the same
  components (bento cells as post cards, tags, the notify card); only the
  long-form article typography (.prose) is blog-specific.
