/* ================================================================
   MOBILE FIXES  ≤ 768px  — case study
   ROOT CAUSES (found with DevTools scrollWidth scan at 390px):
   1. .wall-art / .wall-notes / .ba-step / .ba-bridge lack min-width:0
      so their parent 1fr grid tracks expand to content min-content
      (wall → 566px, ba section → 881px instead of 354px)
   2. .frame.scrollable img uses width:auto + height:300px + max-width:none
      so the image takes its intrinsic width from aspect ratio, forcing
      every ancestor wider
   3. <figure> has browser-default margin:1em 40px that subtracts 80px
      from usable frame width on mobile
   ================================================================ */

     48×20 while it renders 20×48 — causing visual misalignment.
