# US-04 — Move and cook in the shared kitchen

**As a** player,
**I want to** walk my cook, grab ingredients, chop, cook, plate, serve, and wash,
**so that** I can complete orders with my hands.

## Acceptance criteria
1. Keyboard (WASD/arrows) moves the cook smoothly in 8 directions without diagonal
   speed boost; the cook stops at walls, counters, and other players.
2. One action key (`Space`/`Enter`) interacts with the tile(s) in front, choosing the
   sensible verb: pick up, start/hold work, place, plate, serve, wash, trash.
3. Holding the action key performs progressive work (chop ≈ 0.9 s, cook auto-runs,
   wash ≈ 1.2 s) with a visible progress ring.
4. One carried item per player; the carried item is drawn above the cook and its
   form (`raw`/`chopped`/`cooking`/`cooked`/`burnt`/`plated`) is visually distinct.
5. Reach is 1 tile in front (plus a 0.6-tile forgiveness radius); out-of-reach presses
   give an explicit "move closer" nudge rather than doing nothing.
6. A contested target resolves deterministically: one winner, and the loser gets
   visible `denied` feedback — never two players holding one item.
7. Serving a wrong dish is refused with feedback and the order survives.
8. The full chain is possible without dead ends: dirty plates/pots return to the sink
   and come back usable; trash always accepts an item.
