thejayman77 950c7ceb57 Playable Android table
The game runs on device: verified on a Pixel 10 Pro emulator (Android 17) by
installing, tapping through a hand, and confirming it advanced pre-flop to flop
with correct pot, folds, and re-offered action.

App:
- :app module on AGP 9.2.1. Note AGP 9 has built-in Kotlin support, so applying
  org.jetbrains.kotlin.android conflicts with it ("extension with name 'kotlin'
  already registered"); only android.application + kotlin.compose are applied,
  matching recipeze.
- PokerViewModel runs a continuous cash game and publishes to Compose.
- Compose table: opponents, board, pot, hero, action bar with a raise slider.

Frames are queued, not conflated. An all-in runout emits flop, turn and river
microseconds apart; pushing those into a StateFlow would collapse them and the
board would jump from empty to complete. The engine's suspending observer sends
into a Channel, a consumer paces each frame, and only then is StateFlow updated
— so backpressure paces the engine rather than the UI dropping frames. Three
tests cover this, including a characterisation test showing a conflating
StateFlow does lose the intermediate frames.

Assets:
- tools/generate_card_assets.sh rasterises the SVGs into four density buckets
  using sips, which renders SVG directly — no librsvg or ImageMagick.
- Resource names are prefixed card_ because Android resource names may not start
  with a digit (10_of_clubs would be rejected).
- CardArt.kt maps deck index to drawable via static R references, so R8 resource
  shrinking cannot strip the artwork the way getIdentifier lookups would risk.

Layout fixes found by actually looking at the running app: five opponents did
not fit a fixed-width scrolling row (Enzo was off-screen), the header collided
with the status bar clock, and the board floated against a large dead space.

Tests: 52 -> 55, green on jvmTest and testAndroidHostTest.
