/* ============================================================
   Riveryn — guide pages on the "First Light" system (issue #1244)
   Loads AFTER first-light.css and only adds guide-page patterns:
   hero paper artifact, numbered loop steps, curve + plate panels,
   the 7-day plan list, and the worksheet download card.
   Legal pages stay on styles.css — do not link this there.
