/* ==========================================================================
   MF Automations — Proposals
   Design system: "compliance matrix"

   The visual language is lifted from the artifact of the trade: a compliance
   matrix. Hairline table rules, a left rail of monospace requirement IDs,
   status chips. Section markers use real solicitation vernacular (§, Exhibit,
   Addendum) rather than decorative 01/02/03 — the numbering encodes something
   true about the content.

   Colour discipline:
     gold  = action + verified. Nothing else may use it.
     flag  = a caught disqualifier. Appears deliberately, rarely.
     gate  = a hard gate marker (pass/fail screen, not a scored criterion).
   ========================================================================== */

/* ---------- faces ---------------------------------------------------------
   Syne and Instrument Sans ship here as VARIABLE fonts. Declaring the full
   axis range in one @font-face lets every weight render from a single file —
   do not add per-weight faces, it will silently download nothing extra and
   fall back to synthetic bolding.
