/* ---- The hero as a Paper figure inset (council 2, T1-1, 2026-10-31) -------------------------------------------------------------
   The section no longer carries data-theme-lock="ink": it follows the site theme on --surface-page, inside the gutter, with a radius and
   a hairline like every other plate. Only #cftr-viewer keeps the Ink lock, and only its canvas is a dark drawing surface (the viewer clears
   to transparent, so the plate is the canvas's own background). The still picture shown without WebGL and the chain ruler sit outside the
   viewer; they take the darkest ink of the theme as their plate (--text-1 on Paper, --surface-sunken on Ink), so the domain colours read
   the same on both. In @layer page, so it beats the hero rules in styles.css (@layer base). */
