 * The palette is lifted from the app's TvPalette (ui/theme/Color.kt) so the site
 * and the television agree. If a colour changes there, change it here too — these
 * are the only two places it lives.
 *
 * No web fonts, no CDN, no framework. The site is served off a box in Jeffrey's
 * house; every request it can't make is a failure mode it can't have.
