/* BluCast — base styles.
 *
 * Light theme, high contrast: near-black text on white, like a modern games
 * publication (cf. flowgames.gg). Cards are white with a soft shadow and a
 * hairline border; sections alternate white / very-light-grey.
 *
 * --accent is overridden per site from the database (see layout/base.html),
 * so every property in the group inherits this skeleton but wears its own
 * colour. Nothing below hardcodes a site colour. */
