/*
 * The public "try it" page for Rosalena Harness.
 *
 * The palette, spacing scale and radii are copied from the desktop app
 * (harness/ui/styles.css) so the page reads as the same product: midnight-navy
 * surfaces, turquoise as the one primary accent, powder blue for secondary emphasis,
 * platinum-white ink. Dark is the base theme; `html[data-theme="light"]` is a real
 * second palette, not an inversion.
 *
 * Everything is written once against the custom properties, so the two themes differ
 * only in colour. Every text/background pair used here clears 4.5:1.
