/* Articles — container (resource 80) and article detail (template 39).
   Built from design/articles/container/ and design/articles/detail/, Ryan's zips
   of 2026-09-19. Decision record: docs/pages/articles.md.

   All rules scoped under .art so nothing here can reach another page. Site tokens
   are read with live-value fallbacks, as the other page stylesheets do.

   CONTRAST: the ICA theme sets h1/h2 colour directly, and a direct rule beats the
   design's inherited colour — that is what rendered home-page headings at 1.14:1.
   Every dark band below restates its own colours. Audit against the live page
   after the first push, never against the design export, which loads no theme. */

/* --- Card hit area ---------------------------------------------------------
   "Read more →" is a decorative <span>, not an anchor. That was deliberate: the
   design puts the link on the title ("titles are the links, no click here"), and
   a second anchor to the same URL is duplicate link text for a screen reader.
   But it renders Catamaran 700 in link blue, so it reads as a control — and a
   control that does nothing is worse than no control. Reported on the live
   Keep reading row 2026-10-06; identical on the articles/ index grid.

   Fixed by stretching the TITLE's anchor over the whole card rather than by
   adding a second one. One link per card, the whole card becomes the hit area,
   and "Read more" sits under it. Safe here because the card has exactly one
   anchor — nothing gets shadowed. The featured card is untouched: it is .art-feat
   and already has a real button.

   Trade-off: an overlay makes the dek unselectable. Accepted for a card grid.
   Focus is NOT suppressed — the title keeps its native ring, so keyboard users
   still see where they are. */
