/* ============================================================================
   UNSTOCKED — design system v2 "The Shop Manual"            (version-stamp v=8)
   ----------------------------------------------------------------------------
   Dark instruments on paper worksheets. Pages are cold workshop paper and ink,
   ruled and numbered like a factory service manual. The things you MAKE —
   build sheets, bench, cards — stay dark stamped plates with the titanium
   burn: the one saturated object on the bench, an anodized part lying on a
   printed page.

   Type roles: Big Shoulders (display, caps only) · Libre Franklin (text) ·
   Courier Prime (every value: prices, specs, dates, section numbers, stamps).

   Legacy token NAMES (--bg, --surface, --accent, --ink-muted, …) are kept as
   aliases so existing per-page <style> blocks keep resolving; the `.plate`
   scope remaps them to the gunmetal instrument palette, so one component
   vocabulary renders correctly on both surfaces.
