/* ==========================================================================
   ART NOUVEAU — one page. Loaded on a/art-nouveau.html.

   Founder, 2026-09-26: the page is Annie's Claude artifact, shell excepted
   (its side panel and toolbar are not ported; the shell's rail and action
   bar stay). One arched lithograph sheet on the teal ground; the hero and
   the record are its two halves (.an-sheet--top, .an-sheet--rec), joined
   without a seam. The line that encloses every heading is drawn by
   art-nouveau.js. Every rule is scoped to .an-page / .an-stage / .an-rec;
   the shell is never restyled.

   Layout reads the width of the shell's main column, not the viewport:
   .an-stage and .an-rec are inline-size containers named "an".

   Colour. The record's colours "as built" (listed first: the record's
   Colour row reads the first eight hex values in this file): #F2EAD8 #2A2620 #2F5D50 #B08D4A
   #B4737A #55503F #5E5647 #8A4650. Page values added with the artifact
   (flat lithographic tints; not part of the record's palette):
   paper-2 #EADFC6 · ochre #D6AE56 · sage #8FA67F · sage-2 #C9D2B1 ·
   orange #C47A4B (in the figure drawing) · rose tint #E8C9C0 ·
   plum-d #7E3F49 (plum darkened for headings on tints, WCAG AA).
   Contrast, body sizes: ink/paper 12.6 · paper/plum 5.7 · #1F2A20/sage 5.6 ·
   plum/paper 5.7 · plum-d/sage-2 5.0 · plum-d/rose tint 5.0 ·
   umber/paper 6.1 · #7A6128/paper 4.9 · paper/teal 6.3.
