Adds `when_above` conditional pins, resolved per position in
TileShape.at: one graphic can mean two things (the gates' $32 is both
wall base course and counter front), and a flat pin has to pick one.
Gates get half-height counters and level walls.
Pokemon Tower gains a buildings entry -- it is the drawing the map edge
cuts off, sealed on the north -- and the Indigo Plateau statues are
built like the gym statues.
Fixes: grass stands one full-height clump per tile instead of two
half-cut stubs at different depths; ledge pillars drop to ledge height;
a prop only rides furniture when its own cell is blocked (chairs were
being lifted onto tables); and the caves had water and rock pinned
backwards, which stood the Seafoam sea up as rock and cut trenches
through Mt Moon. No cave tile is below the datum now.
Extends the shape profile from ten tilesets to twenty-three -- 1,190
pinned tiles over ~130 maps -- surveyed against the standard the
finished interiors set: one 16px wall band carrying its built-ins,
half-cell counters, bookcase-collapsed shelving, thin-pool plant
standees, objects riding the furniture they are drawn above.
The recurring failures were rooms sunk into ponds by the three
stale-cache water ids (collision is per cell, so one trapped tile sank
its neighbours too), counters and cave edges towering to 32-48px,
racks fusing into deep monoliths, and anything in a walkable cell --
stools, tables, staircases, gravestone arches -- vanishing into the
floor.
Also fixes the door fold overwriting profile pins: it replaced the
resolved shape unconditionally, so stair pins on tiles their tileset
lists in doorTiles (Celadon Mansion, Pokemon Mansion 3F) silently did
nothing.
Flowers stand as 1px animated cutouts on their own pulled mesh (own-cell
flowers hide behind the walker, the cell south still overdraws feet).
Cuttable bushes, gym statues (single-block plinth) and Lt. Surge's trash
cans stand as 5-voxel prop cutouts; prop_ground names the tile painted
beneath. Block edits refresh meshes in place instead of blinking to 2D.
