/* Bayou Barrier — brand guide v1
   Ink #17191C · Access #4BB6E8 · Alert #E2593C · Paper #F6F4EF
   Wordmark: Roboto Slab 900 · Tags: JetBrains Mono · Body: Inter

   Design language: the logo mark is a filtered-traffic grid — coral (blocked)
   over blue (passed) — read against a barrier line. That grid/gauge grammar
   is reused across the page (hero gauge, spec-sheet coordinates, step marks,
   the closing stamp) instead of stock card/icon/badge patterns.
