/* ===================================================================
   GLYCOBARRIER — glycoobarrier.com
   Built on Bootstrap 5 (CDN) + this override sheet.
   Palette: deep pine green + burnt-rust + antique gold, taken from
   the bottle's own label — a fresh combination, distinct from every
   other build in this project (not reused: crimson/copper, navy/
   copper, teal/gold, indigo/mustard).
   Type: 'Open Sans' (headings, 700/800) + 'Roboto' (body) — the
   reverse pairing of the Roboto-Slab+Roboto combination used
   elsewhere, so the type rhythm reads differently.
   Every major section uses a distinct visual mechanic: flip-cards
   for ingredients, a ledger-style list for benefits, a connected
   3-node flow for mechanism, and a dedicated "banner vs FAQ" compare
   panel for the guarantee-language conflict — no repeated pattern.
   Hero signature: "The Glucose Trace" — a slim, gently-undulating
   line-graph with tick gridlines and a single marker travelling
   smoothly along it on a loop, representing steady (not spiking)
   levels; distinct from every other animation used elsewhere (no
   vessel/cell flow, no circuit trace, no flame, no neural spark).
