/**
 * Ebook Store - admin settings screen.
 *
 * Built on custom properties, keyed to the WordPress admin accent colour.
 *
 * Deliberately a single LIGHT palette. The WordPress admin *content area* is
 * light in every core colour scheme (Default, Midnight, Ectoplasm, Coffee, …) —
 * only the menu/toolbar change. An earlier version followed the OS via
 * `@media (prefers-color-scheme: dark)`, which turned these cards dark on a
 * dark-OS while WordPress's own text stayed dark, leaving text unreadable. The
 * fix is to NOT follow the OS: match the admin content area, which is light.
 *
 * .ebook-admin-dark is provided as an explicit opt-in for the rare dark-admin
 * plugin that also darkens the content area; nothing sets it automatically.
 *
 * Logical properties (margin-inline, inset-inline) are used throughout so the
 * layout mirrors correctly for Arabic and Hebrew.
