+
+- The owner's description was lost in kandown; chosen in chat: bag rows light up and the card
+  shows it while Shift is held. t18 was deleted at the owner's request (to decide later: what
+  blow does when the chosen material runs out).
+- `hud.js` `blowingAll()` (Shift held and not flying, or blowing everything); `selection.js` card
+  ("Everything · mix of N", no swatches so it stays one line) and bag `.on` rows; `previews.js`
+  cursor swatches.
+- `test/play.py`: Shift preview on and off, flying doesn't preview (the bot is put back after,
+  or a later gamepad dig check fails). Tests: `run_all.py --browser` all pass (220 `play.py`
+  checks).
