   call: the cards cap at 46em (~80 chars) and alternate a soft indent, so the old
   109-127-char line is gone by design, at his own request. Even cards carry the same
   --accent-soft wash the explainer pages' .lindex boxes use -- an existing idiom, not a
   new colour. ⚠️ ONE ink for all five paragraphs: the old p:first-child{--ink} emphasis
   rule made the opening paragraph darker than the rest, which read as an inconsistency,
   not an emphasis (Nate, 2026-08-24). Body text here matches the explainer pages (--ink). */
