/* SaturnAI — the one visual language for saturnai.tools and saturnai.dev.
   Served at /design/assets/saturn.css; generated into dist/assets/ by build.mjs;
   saturnai.dev's /assets/css/global.css is THIS file with the font path
   rewritten (tools/sync-kit.mjs). Source: site/saturn.css. Never hand-edit a
   generated copy.

   v2 — the Astra launch grammar (SPEC-ASTRA §2/§3), on the SPEC §2 tokens.
   True black under one sky behind the whole page (the library drawn
   as a galaxy on the -18° ring), a split display hero, a centered claim, a
   16:9 media card, one reading measure, pill controls, hairline-framed
   cards, evidence in place of adjectives.

   THE MECHANISM — the verdict — is unchanged: every surface renders the
   stamped PASS / REVISE / REJECT with its evidence line, and the -18° ring is
   the mark, the focus state and the seal.

   DELIBERATELY ABSENT: gradients, glows, blur, shadows, imagery, badge piles,
   stat strips, bento grids, blanket scroll reveals, the default grotesk. Depth is a hairline
   on white-at-alpha over the canvas — never a gray ramp, never a shadow.

   Faces: Instrument Sans variable (OFL 1.1, wght 400-700 / wdth 75-100) for
   display and body; Commit Mono for labels, values, receipts and numbers.
   Self-hosted woff2 only, font-src 'self'. Both Commit Mono license texts
   ship beside the files. */
