/* ==========================================================================
   POP ART — one page. Loaded on a/pop-art.html.

   Founder, 2026-09-26: the page is Annie's Claude artifact, shell excepted.
   Comic panels on a six-column grid, every panel inside the SAME heavy
   black outline (uniform weight is the rule), flat primaries, Ben-Day
   fields whose dots stay countable, yellow caption strips, speech balloons.
   The shell (rail, top bar, community drawer) is never restyled: every
   rule here is scoped to .pp-hero or .pp-rec.

   Reading matter never sits on a dot field: it sits in a white or yellow
   box inside the panel. Nothing animates; the one interaction is the
   threshold switch, a checkbox, no script.

   Palette, in the order the record's "as built" swatches read it:
   #E4202C red · #FFE01B yellow · #0B5FB0 blue · #000000 ink · #FFFFFF paper
   #FFD5CF red-dot ground · #CFE3FF blue-dot ground · #F3A712 yellow-dot ink
   Pairings (WCAG): ink on yellow 15.9, white on red 4.6, ink on red 4.5,
   white on blue 6.4, ink on either dot ground 15.7+. Red and blue are never
   text colours on white here; they are grounds.
