/* ==================================================================================================
   VEIZIK — preopen site stylesheet (2026-09-20).

   DEPARTURE, STATED: the archived v1 site carried an inline <style> in every page and had no shared
   sheet. That was right for a 25-page tree whose pages were edited one at a time; it is wrong for
   this one, where nine pages share one header, one footer and one table. One immutable, CDN-cached
   file is served once and reused, and a token change lands in nine places at once instead of none.
   The archive under /v1/ keeps its inline styles untouched.

   NOTHING NEW WAS INVENTED HERE. Palette, type scale, spacing and radii are the released site's
   tokens verbatim (web/brand/BRAND.md §2, contrast recomputed 2026-09-10). .vz-strip and .vz-panel
   are brand/layout-frames.css, which is where the last design round put the status strip (R-02) and
   the titled box (R-27) after they were rejected as marks. The wordmark rule is the confirmed R-23
   mark: monospace lowercase, z in the signal colour, raised, with its own bar above it.
