/* =====================================================================
   Roxheiris marketing site: layout + components (served at /app/assets/site/brand.css)
   Design system v2 ("Dawn" kit: poster type, sticker cards, dot grid, diagonal panels).

   Tokens come from the shared files. Every page loads, in this order:
     /app/assets/site/fonts.css   (self-hosted Dela Gothic One, M PLUS 2, DM Mono + Lucide)
     /app/assets/site/roxheiris.css   (palettes, light/dark, base element rules)
     /app/assets/site/brand.css   (this file: site layout only)
   Nothing here redefines a palette colour. The few site-only tokens are the
   --band-* set and --gutter / --nav-h below, plus the --pop-* helpers.

   Theme: <html data-theme="light|dark" data-palette="..."> is set by an inline
   <head> script from localStorage (saki.web.theme / saki.web.palette). Absent =
   follows the OS (roxheiris.css handles that).
   Components are prefixed z-. Only the .z-page body opts into the base reset.
