/* public/style.css — dark glass.
 *
 * Hand-written rather than Tailwind: the admin is served as three static files
 * with no build step, and the CSP on /admin is script-src 'self'. A CDN build
 * would mean either adding a toolchain or punching a hole in that, and neither
 * buys anything a stylesheet cannot do.
 *
 * The glass is three layers that have to agree: a translucent fill, a blurred
 * backdrop, and a one-pixel inner highlight along the top edge. Drop the
 * highlight and the panels look like flat grey boxes; drop the blur and the
 * background bleeds through as noise.
