   15. INDEXED IMAGERY — page heroes and card art

   Every image is addressed by index through a CSS custom property:
       style="--img:url('img/hero-07.jpg')"
   The gradient `art-N` class stays underneath as the base layer, so a
   missing or not-yet-generated file degrades to the existing design instead
   of a broken box. Images are decorative, hence background rather than <img>
   — the semantic copy lives in the h1 and lede beside them.

     Re-declaring the tokens here scopes dark-theme values to the hero subtree,
     so every descendant (h1, lede, crumbs, byline, chips, stat-strip) inherits
     the right colour in BOTH themes from one place, instead of needing a

   The house differentiator. Every article carries a section that states, with
   reasoning, where the prevailing advice on its topic breaks down: what the
   standard rule gets wrong, the conditions under which it inverts, and the
   boundary outside which it should not be applied at all.

   Deliberately styled as a distinct editorial object rather than another
   `.callout`, because it is a structural part of every article and needs to
   read as a section, not an aside. Amber/danger accents signal "this is a
   correction", separating it visually from the blue explanatory voice.
