/* Newzino Timeline daily game styles.
 *
 * Most layout is Tailwind classes inline in the templates. This file holds:
 *   - Sortable drag affordances (handle hover, dragging/ghost states)
 *   - Position badges + Oldest/Newest rail labels so the player can always
 *     see where they are in the sequence at a glance
 *   - Type pill shown during play (context, not a leak — types repeat
 *     within a story)
 *   - Hint annotation (📌 oldest date) when the player asks for the anchor
 *   - Reveal animation (slide-into-correct-position + date fade-in)
 *   - Color-coded slot borders (green/yellow/red) that Tailwind can't keep
 *     consistent across both light- and dark-bg surfaces
 *   - Win badge + confetti celebration on average-reader "wins"
 *     (correct >= 3 OR within_one >= 5)
