SMOOSH level editor

Paint a chamber, watch the validator, then copy the rows array into shared/levels.ts. Legend: # wall  . floor  S spawn  D door  * shard  K socket  B battery  Y power-swap shrine  1–5 alcove mouths with pads a–e (the tool stamps mouth + corridor + pad together so the pair is always axis-aligned and exactly 2 tiles apart — press R to rotate the stamp).

Build a set of chambers with the tabs above the canvas — up to seven, played in order. Play live sends the whole set to the server, which re-validates every chamber and creates a fresh room — share the link and play immediately, no deploy. From the second chamber on, sets get power-swap shrines just like the authored run — paint a Y to place that chamber's shrine yourself instead (one per chamber; in authored mode it must leave every pad, mouth, item and the door reachable, since a shrine is solid). Custom rooms wind down ~10 minutes after everyone leaves; to make chambers permanent, export the rows into shared/levels.ts.
