       Barlow — SIL OFL 1.1. THE BRIEF NAMES THIS "variable: wght 400-700, one
       file". Google Fonts' own metadata records Barlow's axes as [] — it does
       not ship a variable instance from the licensed source (the same finding
       already recorded on `bend-lawn-service-bend-or`'s tokens.css, which
       shares this exact family pair). 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 far under §7's
       100 KB total. FLAGGED for Art Director awareness — no token, weight or
       role assignment changed from the brief. */
