/*
 * familyminderapp.com: one stylesheet for every page.
 *
 * Colours are the app's own (composeApp/src/commonMain/kotlin/app/familyminder/
 * ui/Theme.kt): Teal #0E7C86 / TealLight #5CC6D2, Ink, Slate and Mist, with
 * the warm figures of the app icon as accents. Text links use a darker teal
 * (#0B6A73) so they clear 4.5:1 on both light backgrounds.
 *
 * No inline styles anywhere and nothing loaded from elsewhere: the site's
 * Content-Security-Policy (website/_headers) allows styles from this file only.
