/* ============================================================================
   BEPCO Studio — Site styles
   ----------------------------------------------------------------------------
   Ported from design/mockups/bepco-homepage-mockup.html, section by section.
   THIS PASS: global reset + shell chrome (noise overlay, amber spine,
   classification banner, nav) + the HERO. Remaining sections (ticker, archive,
   field notes, split, footer) are added in later increments.

   Conventions:
   - Colors & font families reference tokens.css (--color-*, --font-*).
   - rgba() translucent tints and letter-spacing / line-height are kept as the
     mockup's EXACT literals (imported verbatim, not invented) — they are not
     tokenized yet (deferred opacity layer + out-of-scope typography metrics).
   - --ease is defined locally below until we do a dedicated motion-token pass.
   ============================================================================ */
