Root cause: featured_pour's empty-media placeholder used an external <use>
SVG (svg class=h-24 w-24 + use href=/icons/lucide.svg#coffee) sized ONLY by
Tailwind utilities. The host Tailwind JIT does not reliably emit utility
classes used solely in a theme block template, so h-24/w-24 could be dropped
from the generated stylesheet; the SVG (no viewBox, no intrinsic size) then
ballooned to fill its aspect-square parent (~350-500px cup silhouettes over
the hero/blog cards). Fix pins width/height geometry attributes on every
<use> icon SVG so size is CSS-independent and deterministic.
