/* ============================================================
   SiteTimeline — architectural datasheet
   Derived from the Alta Roofing IKO shingle brochure: cream paper,
   one bronze accent, condensed display type, letterspaced small-caps
   eyebrows, hairline rules, corner registration marks, square corners.

   Emphasis is expressed by INVERSION, never by a second colour.
   --accent is a tenant variable (patch.js overrides it per company),
   so the same system carries Alta bronze and Bloom sage.
