   framework.css — shared styles for all framework deep-dive pages.

   Per-page color identity is set via --page-accent / --page-accent-soft,

   handles same-page #links AND cross-page jargon.html#term jumps uniformly.

   scroll-margin-top on common targets in case scroll-padding-top is ignored. */
