/* =========================================================================
   MOBILE (<=680px) — real reflow, not a scaled-down desktop screenshot.
   Everything above this point is the desktop/tablet design and is
   untouched by this block. Two things happen below:
   1. The sticky nav becomes a hamburger + dropdown instead of a row that
      overflows into horizontal scroll.
   2. Each fixed 816px "page" stops being scaled down as one rigid unit
      (assets/catalogue.js skips the transform below this same 680px
      breakpoint) and instead reflows at 100% width with its own mobile
      spacing/column rules, so text renders at a real, comfortable size
      instead of a shrunk fraction of the desktop size.
