+### Added
+
+- **"What's new" on update.** The first launch after an update shows a
+  one-time card summarising what changed — like this one, right now.
+  Dismiss it and it never repeats; fresh installs never see it. (#180)
+- **Situational tips.** Two one-time teaches that fire from play, not a
+  tour: staring at a stuck board for a while points you at Hint, and an
+  engaged game quietly mentions the long-press quick-action menu —
+  unless you've already found it yourself. (#181)
+- **UI scale.** Settings → Accessibility now has a UI Scale control
+  (90% / 100% / 115% / 130%) that resizes every menu, button, and HUD
+  element live. The table always fits your screen regardless. (#182)
+- **Hold `/` for shortcuts** (desktop). A reference card of every
+  keyboard binding appears while `/` is held. The onboarding tour and
+  this card now share one binding table, so they can never disagree —
+  the tour's copy had drifted from reality. (#183)
+
