/* Base styles for V2 creatives rendered by NAS.
 *
 * NAS emits HTML using class names `.creative-{id}`, `.creative-header`,
 * `.creative-body`, `.creative-button`, `.creative-button-positive`, etc.
 * and per-creative CSS custom property values (`--positive-button-bg`,
 * `--header-color`, …). This stylesheet provides the rules that consume
 * those custom properties — without it, NAS-rendered creatives fall back
 * to browser defaults.
 *
 * Everything lives inside `@layer base` so pod-theme custom CSS
 * (`@layer pod-theme-custom-css`, declared higher in the cascade by NAS)
 * can override these defaults. Without the layer, unlayered rules would
 * win over any layered rule per the CSS cascade — and operator-authored
 * pod-theme CSS could never override e.g. `.creative-header`.
 *
 * This single stylesheet is inlined into both the live NAS-served creative
 * and the editor preview (cashew assembles the preview document with the
 * on-disk file), so the preview always matches production.
