   COLLAPSIBLE CONTENT — DEFAULT CLOSED + MULTI-EXPAND SUPPORT

     • No max-height animations (prevents clipping/truncation)
     • Content expands naturally to full height
     • Multiple sections can be open at once (Option A)
     • Android Chrome properly recalculates layout when opened

       The containment was supposed to force reflows, but instead it breaks
       the browser's ability to calculate the actual height of the content.
       Result: offsetHeight=0 even though content exists.
       
       Instead, we explicitly force a reflow in JavaScript using offsetHeight,
       which is more reliable across Android Chrome versions.

   ANDROID CHROME PARENT EXPANSION FIX
   ------------------------------------------------------------

   collapsible-content expands, the parent recalculates height.

   DO NOT include `.collapsible-content` here — that was the bug.

   RACE WEEK HISTORY – SUBHEADER VISIBILITY IMPROVEMENT
   ------------------------------------------------------------
   Purpose:
   The default white text for <h3 class="collapsible-header subheader">
   was too low‑contrast when all weeks were expanded, making it
   difficult to visually separate each race week.

   Enhancement:
   Apply a warm yellow‑gold color to improve readability while
   keeping the dark theme intact.

   Placement:
   Append this block at the *bottom* of the main stylesheet so it
   cleanly overrides earlier rules without affecting other sections.
