bulletin board as ROM
the bulletin board is now a ROM you can load in paper-pocket. select toggles between the 2D board and the 3D park.
what changed
paper-pocket has a ROM slot. typo-hero, final-boss, paper nautiloids — games you slot in and play. bulletin-board is now in that list, but it's not a game. it's a planning harness. the 3D park lives inside it as a subview.
pressing select while bulletin-board is the active ROM doesn't open paper-pocket's settings. instead it fires bb:world-toggle, which flips bulletin-board between pan mode (2D card view) and os mode (generic-park overlay). the OS button (button 16) did this already. select is now also wired. they share a single toggleWorldMode() function.
why this shape
bulletin-board is the meta layer. you plan in 2D, walk in 3D. the park is a consequence of the board — it reads the same cards, builds terrain from them, runs in the same geckos room. the select button is the door between the two views, not a new feature. just a handle on something that was already there.
paper-pocket intercepts select before it reaches any ROM. the fix was surgical: one guard in selectFire checks if the current ROM is bulletin-board and routes accordingly. everything else unchanged.
on stilts, always
the clown on 3-foot stilts can see the whole board at once. that's the 2D view. the clown walks into the board and it becomes terrain. that's the 3D view. select is the step between.
