A small canvas pinball engine (src/lib/pinball.js): fixed-timestep physics
with 5 substeps, circle-vs-segment collision, two rotating flippers whose
angular velocity drives the ball, 3 pop bumpers, 2 slingshots, a charged
plunger, 3 balls. Lighting all 3 bumpers "catches" a random Pokémon for a
bonus. Ball-search kicks a wedged ball toward centre; three strikes and it
drains. High score in pdx.pinball.
Hidden like "Who's that Pokémon?" — no nav entry; the two games
cross-link from each other's back-nav, or reach it at #/pinball.
Controls: ← / → (also A/L, Z) flippers, hold Space / the Launch button for
the plunger; on touch, tap the table's left or right half.
Rendering: the canvas is sized from its container with a DPR-capped
backing store (crisp on any display). `_frame()` is exposed so the physics
can be driven headlessly. 3 unit tests for the geometry helpers.
The physics are stable and the game loop is complete; feel (flipper
strength, ball speed, table balance) still wants hands-on tuning.
