/*
 * Page shell for the web build.
 *
 * The stock template pins the game to a fixed box with a rounded border and
 * page furniture around it. This replaces that with a frame that fills the
 * browser window while holding the 16:9 of the 2560x1440 design resolution, so
 * the game letterboxes against the surrounding colour instead of stretching.
 * `!important` is required because the generated markup sets the frame size as
 * an inline style on #GameDiv.
 *
 * image-rendering: pixelated matters as much as the engine-side filter setting:
 * without it the browser resamples the upscaled canvas bilinearly and undoes
 * the point filtering at the very last step.
