  /* --- Typography (brief §2). Two families:
       Anton   — SIL OFL 1.1, static, wght 400 only, no italic.
       Barlow  — SIL OFL 1.1. THE BRIEF NAMES THIS "variable: wght 400–600,
       one file". Google Fonts' own metadata (fonts.google.com/metadata/fonts,
       read at build time) records Barlow's axes as [] — it ships NO variable
       instance from the licensed source. Substituted with TWO STATIC
       instances (400, 600) of the identical family instead of one variable
       file: same face, same two weights, same roles, only the delivery
       mechanism changes (a mechanical substitution, not a design choice —
       house-tech-spec §7.1 treats font delivery as delivery-mechanical work).
       File count is now 3 (Anton 400 + Barlow 400 + Barlow 600), still inside
       design-rules §5's ≤4 woff2 / ≤2 family caps, and the combined payload is
       comfortably under §2.6's 100 KB total. FLAGGED in the build report as a
       brief inaccuracy for Art Director awareness — no token, weight or role
       assignment changed. */

   COVERAGE GAP, recorded per §2.5 rather than silently shipped: U+2011 is
   absent from Anton; U+2011, U+2012 and U+2015 are absent from both Barlow
   instances (measured with a fontTools cmap read against the shipped woff2,
   2026-08-27). None of the three render anywhere in this site's copy — the
   only separator used is U+00B7 (·), and copy.md carries no em dash — so the
   gap is latent, not a mid-sentence split. Not narrowed, per house-tech-spec
   §8's reasoning: narrowing would make the declared range per-site, which is
   the one property it exists not to have.
