The previous attempts (#97/#98) capped a wrapper element's max-width and
relied on the canvas's width:100% resolving against it — but winit observes
and sizes the *canvas element itself* (via ResizeObserver on its content box),
so the wrapper cap never reached the surface and /play still panicked at
2560x1440 on a 4K@150% viewport.
Use the canonical mechanism instead: set the primary Window's
`resize_constraints { max_width: 2048, max_height: 2048 }`. On web, Bevy maps
this to winit `set_max_inner_size` → the canvas's own `max-width`/`max-height`
style, so the wgpu surface can never exceed wgpu's downlevel_webgl2
max_texture_dimension_2d (2048). play.html mirrors the same `max-*` directly on
#bevy-canvas (belt-and-suspenders) and centres the letterbox with margin:auto;
the obsolete wrapper + clamp script are removed.
