/*
 * Page shell for the web build.

 * frame that fills the window while holding the 16:9 of the 1280x720 design
 * resolution, so the game letterboxes against black instead of stretching.
 *
 * `!important` is not decoration: the generated markup writes the frame size
 * as an inline style on #GameDiv, and inline styles outrank the sheet.
