<syntaxhighlight lang="text">Seed v1 (Gemini-friendly, minimal + stable)

Build a playable isometric-lite roguelite room prototype in a single HTML file (Canvas).

Hard rules:
1) All game logic uses WORLD/TILE coords only (movement, collision, exits, room transition).
2) Isometric projection is rendering-only.
3) Player must never disappear:
* Draw a procedural SD mech (white armor + blue visor + outline) as the default sprite.
* Optional: allow replacing with an embedded dataURL sprite later, but NOT required for v1.
4) Room loop:
* One room with 4 exits indicators.
* Exits trigger room transition to a new generated room (rx,ry changes).
5) Weapons:
* Q/E cycles Rifle / Shotgun / Missile; HUD updates.
6) Debug:
* F1 shows player tile coords + room coords + exit triggers.
* F2 shows collision circles and hit logs.

Acceptance:
* Player visible always.
* Exits always work.
* Q/E switching always works.

這顆種子故意「不提附件、不提貼圖載入」，先讓它用程序畫出你的白格林特 SD vibe。
等它穩了，我們再加一顆超小的 Patch：把你那張白格林特轉 data URL 內嵌進去（一次就成功）。
