/* ─────────────────────────────────────────────────────────────────────────────
   Loghmac site design system v2 — shared by index.html, showcase.html, legal.html.
   One file so the three pages cannot drift apart visually.

   Named site.v2.css (not site.css) on purpose: the Arvan edge kept serving a
   stale /loqme.apk for an hour past its max-age, and a stylesheet that goes
   stale next to a fresh HTML file renders an unstyled page. A new filename
   cannot be shadowed by a cached old one.

   Palette = the app's own emerald brand (LqColors.kt) so site and product read
   as one thing; every colour has a dark counterpart — a health app gets opened
   at night. Typeface = the same self-hosted Vazirmatn the Android app ships.
