Cake Stall rules: a tested `cake-stall/order.js` where you memorise a seeded order of cake layers shown for a few ticks and stack them back in that order, in a two-file pull with a test file that runs in under a second #366

I added the Cake Stall rules in cake-stall/order.js, with its tests in cake-stall/order.test.mjs, and nothing else in the repository changed. bun test cake-stall/order.test.mjs passes 9 tests in about 39 ms, well under one second, and bun x tsc --noEmit reports no errors. I didn't run scripts/gate.ts or the full bun test, so the forge's check will be the first full run.

I also didn't find docs/VISION.md in the clone, so I worked from the issue text and from tide-crossing/causeway.js and apple-bobbing/tub.js.

The rules

• Shape: the module uses the same UMD shape as tide-crossing/causeway.js and exports CakeStall in the browser. It also exports LAYERS, LIVES, ROUNDS, restart, orderFor and describe.
• Orders: start(seed) gives round one with 3 layers drawn from sponge, jam, cream and icing, and the number of ticks it stays shown. Round r has r + 2 layers and is shown for 3 + length ticks. The mulberry32 generator is seeded from the seed and the round number, so an order depends only on those two. restart gives the same first round again.
• tick: it counts the showing time down and hides the order at zero.
• place: it adds a layer once the order is hidden.
• Refusals: each refusal returns the same state with a reason. The reasons are game-over, unknown-layer, order-shown and order-hidden (ticking an order that is already hidden).
• Wrong layer: it costs one of three lives and clears your stack. The same order is shown afresh for the full showing time.
• Right stack: it scores 10 points per layer and opens the next round with one more layer.
• Ending: losing the last life gives "Out of lives: N rounds served, score …". Finishing round 8 gives "You win: all 8 orders served, score …".
• HUD: the state carries round, lives, score, placed, order, shown, status and line.

Tests: they cover each rule in the issue and call the module directly, with no page, renderer or server.

Left out: no page, no catalogue entry, and none of the files you listed as off limits.
