+  (agent) Done in six commits; all tests pass. Water: it did run out, just slowly. Pools now pour
+  off ledges several times faster (a 100-wide pool empties in about 50 s) and leftover film drains;
+  rain from steam spreads out downwind, so a waterfall into a hot shaft no longer refills its own
+  lake. Found and fixed: steam or smoke trapped in a pocket never finished, and rain landing on
+  steam deleted water. Piles near the bot now sort, quickly. Faster with identical results: the
+  roof scan (4.6 -> 1.9 ms on a quiet Huge world) and the heat pass. A loaded world starts around
+  the bot first (Huge, first 10 s: 15 -> 5.5 ms a tick, worst 80 -> 16 ms). Seven duplicates merged
+  and six large files split. Seeds make the same worlds as before. Please check: pour a pond off a
+  ledge; stand by a pile of ore on ash; load a Huge world and fly around in the first 20 s.

+## Context
+
+- When loose material (rubble, dirt, ore) lies on top of or against solid rock, the two are hard to tell apart in the smooth look: the loose grains blend into the rock under them, so it's unclear where the solid ground starts and what is still to dig. The owner's screenshot: `/home/aaron/Pictures/Screenshots/Screenshot_20261024_214546.png` (a dug-out area around the bot where loose copper-coloured rubble covers the rock).
+
+## Subtasks
+
+- [ ] Find what makes them blend (similar colours, lighting, the smooth look's edge blending, no outline between loose and solid)
+- [ ] Give loose grains and solid ground a clear visual difference (for example an edge or shading on solid rock, a different texture or brightness for loose grains), in both looks

+## Context

+- Blowing with the Pneumatic nozzle has no range limit: with the cursor outside the reach circle around the bot, blown grains still fly all the way to the cursor, and the farther you aim, the farther they go. Sucking only works inside the circle. Blowing should be limited to the same reach.
+- Cause: `nozzle()` in `src/sim/vacuum.js` works out a distance capped at the reach, but `toolBlow()` aims every grain at the cursor itself rather than at that capped point.

+- [ ] Aim blown grains at the cursor only when it's inside the reach; outside it, aim at the edge of the reach in the cursor's direction
+- [ ] Make the blow preview show where grains will land when the cursor is out of reach
+- [ ] Check thrown bars still match (they already aim at the capped point)
