/* ---------- agenda band ----------
   Recovered 2026-09-02. These six repos were scaffolded from a stylesheet that had
   lost this block, so .agenda rendered as run-on inline text ~700px tall inside the
   masthead. 87 of 93 repos carry it; these were the exception, and they were also the
   six the estate sweep could not see. See course-builder/references/field-notes.md.

   .a3 does NOT reuse the donor's `color: var(--amber-ink)`: that pair falls below
   4.5:1 against --amber in all six palettes, which is the same failure the sweep
   flags on the wellbeing courses. The literal below is the darkest tone of this
   repo's own amber-ink that clears 4.5:1, so the band stays bright. Recompute it if
   --amber changes. */
