/* ============================================
   Synexar — Launch 2026 dress: "The Unbroken Line"
   Additive layer. Loaded AFTER each page's inlined styles so it wins
   the cascade at equal specificity. All new selectors are l26-prefixed;
   the only overrides of existing selectors are the fixed-header offsets
   and the footer masthead lockup.

   Palette discipline:
   - --line-accent  #b3573a  terracotta: the Line, launch accents
   - --line-ember   #d98e4a  ember: MOTION-ONLY (the tip riding the Line)
   - --launch-ground #faf6ef parchment ground
   - #B83848 reserved red: fragmentation dashes ONLY — its one sanctioned
     static appearance in the launch identity
   ============================================ */
