/* ============================================================================
   Clearline visual reset — nav skin (#73). Restyles the SAME `.mnav` markup +
   marketing-nav.js to the claude.ai-style system, using tokens.css. Reset pages
   load this INSTEAD of marketing-nav.css:
     <link rel="stylesheet" href="/assets/css/tokens.css">
     <link rel="stylesheet" href="/assets/css/reset-shell.css">
     <link rel="stylesheet" href="/assets/css/reset-nav.css">
   Legacy (not-yet-reset) pages keep marketing-nav.css untouched — staged rollout.
   Brand mark stays the current six-line fallback until clearline-design #7 lands.
