/**
 * Figma source: Board UI → medical profile dashboard → Frame 126 (node
 * 3950:5936). Alert feed: tinted icon circle, title + description, and a
 * soft date pill absolutely pinned to the row's top-right corner.
 *
 * The feed runs flush to the card's bottom edge and clips there (the card
 * keeps its 10px inset on the other three sides only) — per Figma, where
 * the third alert row is visibly cut off by the card bounds. The scroll
 * content itself ends with a 10px pad so the last alert doesn't sit hard
 * against that edge once you reach the bottom, and a card-colored gradient
 * fades in over the top edge while scrolled so rows dissolve out instead
 * of being sharply cut by the header.
