/* ───────────────────────────────────────────
   Content blocks
   Rendered by build.mjs from `:::name` markers in markdown.

   Monochrome by constraint, not by preference: the design tokens in global.css
   define a greyscale system, so these blocks separate by ICON, LABEL and RULE
   WEIGHT rather than by hue. That also means they stay legible in greyscale
   print and for colour-blind readers without a second code path.

   Mobile-first throughout. Every interactive target is >= 44px.
   ─────────────────────────────────────────── */

/* ── Token bridge ────────────────────────────────────────────────────────────
   This file arrived from another project and reads `--color-*`. NONE of those
   names exist in site.css, whose tokens are `--ink`, `--line`, `--surface-*`.
   Every var() below was therefore silently falling through to its hardcoded
   grey fallback, so the blocks rendered in a palette the rest of the site does
   not use (#111 instead of #1c1c1e, #5b5b5b instead of #55555c, and so on).

   Mapping them here rather than renaming 60 var() calls keeps this file a
   drop-in from the kit, and keeps site.css — the design system — untouched.

   `--color-border` does NOT map to `--line` (#ececee). That token is for
   hairlines between blocks of text on white; these blocks use their border as
   the visible edge of a container, and #ececee is invisible at that job. It
   maps instead to the same #d9d9de site.css already uses for form-field edges,
   which is the existing site's "this is a real boundary" grey.
