Correction to the previous canvas clamp (#97), which would NOT have fixed the
crash. It capped the wrapper to the device's gl.MAX_TEXTURE_SIZE, but that's
the hardware limit — on a 4K/integrated GPU it reports 8192+, so the wrapper
was never actually capped and the 2560-wide surface still exceeded the limit.
The real ceiling is wgpu's, not the hardware's: on wasm Bevy creates the device
with Limits::downlevel_webgl2_defaults() (forced by WgpuSettingsPriority::WebGL2
in solitaire_web/src/lib.rs; see bevy_render-0.18.1 settings.rs), whose
max_texture_dimension_2d is a fixed 2048 regardless of GPU. So the cap must be
the constant 2048.
(For the record: the reporter's display is 3840x2160 at 150% scale → a 2560x1440
logical viewport, which is the 2560 in the panic — nothing hardcodes 1440p.)

Rhys hit a fatal wgpu validation panic loading /play on a 1440p display:
Surface::configure ... Requested was (2560, 1440), maximum extent for
either dimension is 2048
The earlier scale_factor_override(1.0) fix only neutralised HiDPI (CSS×DPR);
it didn't help when the *logical* viewport itself exceeds 2048. `fit_canvas_to_
parent` sizes the wgpu surface to the canvas's parent, so a 2560-wide viewport
configures a 2560-wide surface — past WebGL2's 2048 per-dimension limit on
laptop/integrated GPUs, and the panic kills the WASM thread on the first frame.
Wrap the canvas in #bevy-wrap and, before init, clamp that element's max-
width/height to the device's actual gl.MAX_TEXTURE_SIZE (falling back to the
2048 WebGL2 floor). fit_canvas_to_parent then never produces a surface larger
than the GPU allows. Only devices at the 2048 floor letterbox (centered); GPUs
that report 4096/8192 still fill the viewport.

play.html now loads solitaire_wasm.js alongside the Bevy canvas and
exposes the same window.__FERROUS_DEBUG__ object as /play-classic.
The bridge runs an independent SolitaireGame (WASM logic layer) seeded
from ?seed= / ?draw3= URL params; Bevy renders the visual game in
parallel without coupling.
Methods exposed: seed, state, legalMoves, moveHistory, snapshot,
applyLegalMove, applyMove, draw, undo, serialize, fromSaved, newGame,
failureReport, replayPayload, runAutoplay — matching the /play-classic
contract so the shared Playwright harness targets either route without
modification.
cycle_metrics.js: add --route play-classic|play flag (default
play-classic). Routes to /${route}?seed=N. The resume-overlay clear
step is skipped for /play since the Bevy build uses localStorage-backed
WasmStorage, not a #resume-overlay element.
