/**
 * AWB Newsletter — frontend styles.
 *
 * Common / Theme / Astra rules are deliberately UNLAYERED: most theme CSS
 * (Tailwind v3 builds, classic themes, WP preflight resets) is unlayered too,
 * and unlayered CSS always beats anything declared inside a cascade layer —
 * so a layered ruleset would lose to the theme's `input { ... }` reset.
 *
 * Only the Tailwind-mode section lives in `@layer awb`, because there the
 * markup carries utilities and plugin CSS must never outrank them (utilities
 * in Tailwind v4 are layered; in v3 they are unlayered and win anyway).
 * Keyframes are declared outside any layer.
