+## 2026-10-24: t20: pick up what you click, blow out what's in hand (Claude Code, Codex)
+
+- After discussing options with the owner: one Vacuum, a drag locks onto the material it starts on
+ (Shift: everything), and `GAME.blow` is "the hand" (click/Q/E, Ctrl+click mix). Empty materials
+ leave the hand; an empty hand blows nothing; a pickup fills an empty hand. Removed `GAME.collect`,
+ R marks, Ctrl+right-click, `openVacuumMenu`, `ensureBlow` and the `.vpick` styles.
+- Files: `src/ui/{actions,selection,hud,state,previews,build-menu,info,notebook,session}.js`,
+ `src/sim/{vacuum,progress}.js` (`toolVacuum` returns the first material picked up),
+ `src/styles/style.css`, `test/play.py`, `test/t_basics.js`.
+- Tests: `run_all.py --browser` all passed (play.py 214 checks). Screenshots `shots/t20-*.png`
+ (empty hand, one item, mix, 900px).

First steps
1. Drill down a little. Stone falls as rubble; coal (dark seams), copper ore (green speckles) and clay (reddish) come loose too.
- 2. With the Vacuum, left click to pick up loose materials. To take only coal, copper ore, rubble or clay, mark what you want in the vacuum menu (F).
+ 2. With the Vacuum, left drag to pick up the loose material you click. Shift takes everything.
3. Build (3) a chamber of stone wall blocks with a one-block vent in the roof, a floor of clay Grates, and an Ingot mold right under the grates. The notebook's Blueprints tab has this as a starter design.
- 4. In the vacuum menu (F), mark coal and copper ore with ⬆ to blow both. Fly inside (the bot passes through what you build) and right click to blow an even mix onto the grates: about 50 of each. (Ore first and coal on top works too; coal buried under ore will not light.) Light a coal grain on top with the Igniter.
+ 4. Ctrl+click coal and copper ore in the bag to blow a mix. Fly inside (the bot passes through what you build) and right click to blow an even mix onto the grates: about 50 of each. (Ore first and coal on top works too; coal buried under ore will not light.) Light a coal grain on top with the Igniter.
5. When the ingot sets, bars drop out of the bottom of the mold onto whatever is under it. Leave one open block under it: a belt below that carries them off, or vacuum them up. Leftover metal stays for the next firing. Ingot molds empty themselves: bars, junk and scrap drop below, slag is thrown away and the grate above is raked. Removing any mold returns its set metal to your bag: whole bars as bars, the rest as scrap.
Screw tubes carry grains and whole bars: feed bars in from a belt, turn corners and unload at the mouth.
6. Blow the bars into the trade dock: they sell the moment they drop through its grate, and bars pay far more than ore. Watch the Market page for orders that pay double. Money buys belts, screw tubes and fans; pay down the claim there too.
