/* ============================================================
   THE BROADSIDE v2.1 - aexagon.com design system
   Single source of truth for the marketing pages
   (index, /work, 404). discovery/ and learn/ are standalone.

   Rules this file enforces (Brand Guidelines v2.0):
   - Red owns brand + action. Yellow owns ONE highlight bar
     per page (.hl), ink text on the bar, never yellow text.
   - Left-aligned, square corners, no gradients, no shadows.
   - Tanker 400 all-caps display / Supreme 300-500 body only.
   - No em or en dashes in any copy. Ranges use hyphens.
   Values are extracted verbatim from the shipped homepage.
   Do not edit values here without checking every page.
