/*
 * The site is painted from the same tokens as the product — see docs/look.md, which is the
 * authority. Two rules from that document carry over and are not a matter of taste here
 * either: the neutrals are neutral rather than blue-tinted, and there is no coloured bloom.
 * A 26px glow is what makes a colour read as neon, and this product deliberately is not.
 *
 * The palette in the app is measured against the bar composited over a white document. That
 * problem does not exist here — the page owns its own background — so these are ordinary
 * contrast ratios against #05090c, all comfortably past WCAG AA.
