 * The identity is an arcade cabinet: near-black violet, a volt-green primary
 * and an ember-pink secondary, hard 4px corners, and a wide geometric display
 * face used only in uppercase. The palette deliberately matches the embedded
 * games in static/games/ so the shell and the games read as one product rather
 * than a site with games pasted into it.
 *
 * Dark is the default and the real identity. Light is a supported override
 * rather than the base, which is why the media query below is `light`.
