/* AR Readiness Checker — static rail styles.
   SR-21 enterprise-design conformance (FOUNDRY build #3, run #35, 2026-08-21).
   Token scale is IDENTICAL to product-photo-prep/web-static/styles.css — the
   design system's single source of truth (enterprise-design token names + values, --r/--rs
   radii, --ease, compact enterprise type scale, Urbanist headings over Inter body,
   pill controls, hairline --br borders, signature indigo->pink/amber gradient on
   the conversion CTA). Dual-mode: OS preference AND explicit [data-color-mode].
   CRUCIBLE ratifies mobile/dark/font at the Day-5 gate.

   Security-justified deviation (ALG-3 S1/S3/S4/SR-8): fonts are SELF-HOSTED via
   @font-face (font-src 'self'), never a third-party font CDN — preserves the
   zero-third-party-network posture and the locked default-src 'none' CSP. Faces
   ship in ./fonts/ at deploy (OFL); if absent, the stack degrades to system sans
   with zero breakage. */
