/* =====================================================================================
   ABOUT — the page that explains the piece (about.html), plus the one quiet link that
   points at it from the globe (index.html).

   It rides on styles.css: the palette variables (--ink, --ink-soft, --ink-faint, --line,
   --gold, --serif, --sans) and the warm sepia ground come from there, so this page stays
   in step with the piece if the palette moves. Nothing here is a plate: no borders, no
   rounding, no shadows. Structure is carried by whitespace and single hairline rules,
   and nothing is set below 13px.

   Everything page-level is scoped to .aboutpage so index.html can load this file purely
   for .lg-about, the link in the legend, without inheriting a scrolling document.
   ===================================================================================== */
