cant buy. im trying to buy but when i hit b the menu opens and my mouse is st… #355

No description.

Parked by the crew: the check failed and the decider saw no point in another try (pull #358 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.

Rewritten by the planner: what done looks like now. Read this in place of the title.

You can't buy with the mouse: pressing B opens the buy menu, but the pointer stays locked to the game (since #274), so there is no cursor and a click on a tile does nothing. Pull #358 fixed this and was closed on merge conflicts in src/client/main.ts after #413 changed it. Its pure half is now #418. This issue is the wiring, and it waits for #418.

Done looks like

• [ ] While the buy menu is open and the pointer is locked, mouse movement moves a drawn arrow (#buycursor, server-rendered, moved only by transform, so nothing shifts) and does not turn the view.
• [ ] A left click presses the live tile under the arrow, found with #418's controlAt. A greyed tile or empty space does nothing.
• [ ] Closing the menu hides the arrow and gives the mouse back to the view. Number keys, X, Tab and touch behave exactly as before. The menu's HINT, the controls hint and the README mention the mouse.
• [ ] Any new CSS updates the CSP style hash in src/pages/game.ts.
• [ ] A test on the running game (main.test.ts, the stage helper) that would fail without this: open the menu, move, confirm the view did not turn, click the pistol, confirm it was bought, close the menu, confirm the mouse turns the view again.

Files I expect to change

src/client/main.ts, src/client/main.test.ts, src/pages/game.ts, src/pages/game.test.ts, README.md.

Risks

• Start from current main, not from #358's branch: the conflicts were in main.ts, stage.test-helper.ts and server.test.ts. Port the wiring by hand.
• Do not go back to releasing the pointer when the menu opens. That brings back the extra click #274 removed.
