New helpers
- picogame_road.Road - drive the native pg.road_edges + Canvas.road pair from
  human units (curve periods and swing in px, hills via set_grade, safe int32
  phase wrap), plus the queries games kept re-deriving: curve_at() for
  centrifugal physics and row_of/half_of/edges_of for placing sprites on the
  road. Perspective is the device-proven picobike model; picobike itself now
  runs on it.
- shapes.masks(mask_list, color) - the multi-frame from_mask that was missing
  between from_mask and atlas.
- shapes.tileset_colors(..., gap=N) - a transparent mortar edge per tile, so
  touching same-colour tiles stay readable as tiles.
- Raycaster.set_cell(x, y, v) - change one world cell at runtime (doors,
  gates); keeps the caster grid, solid() and .map consistent and re-casts even
  for a standing camera.
- Shake(scene=None) - the trauma model without a scene: tick() publishes
  .ox/.oy for strip-rendered games (road, raycaster, mode-7) to spend in their
  own camera params, since set_view never moves a StripDraw.

Behaviour change
- Pool keeps its own in-use bit (`pool.alive`), so sprite.visible now means
  only "draw this": blinking a pooled sprite no longer hands its slot to the
  next spawn(). Every existing `if not s.visible: continue` guard still reads
  correctly, so no game needs changing; free() of a foreign sprite now raises
  ValueError instead of silently hiding it.

Also: picogame_scene.View.set_tile_prop (flip a tile TYPE's flags at runtime),
picogame_script (story scripts as generators), documented traps in
Raycaster.draw (its row 0 is the view's top, not the screen's) and the
billboard idiom (a Scene draws in add order, so sorting your own list
reorders nothing).

0.2.0

The engine these helpers sit on shipped in CircuitPython 10.3.0 — picogame is no
longer a fork-only module, so the libs get a minor bump to match.

picogame_scenebake: bake a level's scene JSON on the device, so iterating on a
  level no longer needs a tools/scene_build.py pass after every edit. Entry point
  is picogame_scene.load_json(pg, path); it is a function on purpose, so the JSON
  text and the parse tree stay locals and die on return — measured, that is the
  difference between a transient startup spike and a permanent cost. Colour-
  tileset levels only; PNG art still needs the desktop quantizer.
picogame_tiles: says plainly that a scene loaded by picogame_scene should use
  view.tile_has(name) instead of a parallel bitfield, and that the eight flag bits
  are all there are — there is no separate custom range to go looking for.
picogame_i2cpad: PICOGAME_I2C accepts a bus name.

0.1.35

picogame_options: the row list can be rebuilt at runtime.
  set_rows(rows, sel=0) replaces the rows and repaints, normalising the new ones like the
  constructor did - so a row written by hand or restored from a save may omit i/value instead
  of raising KeyError on the next render. It is also how a sub-level's rows are swapped in and
  out, which puts a whole menu tree on one widget and one SceneBox layer.
  visible= is now the window height when passed explicitly, instead of collapsing to the initial
  row count, so a list that grows and shrinks (a roster, connected players, shop stock) keeps one
  panel size; show() clamps the cursor and scroll window, so a list that shrinks under the cursor
  cannot IndexError.

0.1.34

Display: one source of truth
  picogame_game.screen()/display() take the board's display from supervisor.runtime.display -
  the primary display CircuitPython selects at boot, or the one a boot.py/launcher publishes.
  Games no longer read board.DISPLAY, so the same file runs on a PicoPad, a Fruit Jam and a
  bare Pico; the simulator and the WASM playground ship a small supervisor shim.
  Verified on hardware (PicoPad + Fruit Jam, dist/hwtest): 12/12 and 14/14 checks.

Fixes
  open_framebuffer(): a failed resolution switch rebuilds and republishes the previous mode
  instead of leaving the board with no display at all until a power cycle.
  picogame_i2cpad: attach() now clocks a wedged bus free (deinit + 9 SCL + STOP + rebuild)
  instead of timing out until the pad is unplugged - the recovery existed but could never run.
  picogame_launcher: detects a shimmed supervisor (sim/playground) instead of assuming a device.
