/*
 * wooary — core UI.
 *
 * Netflix-derived patterns, adapted rather than copied:
 *   - edge-to-edge dark canvas, chrome that gets out of the way
 *   - horizontal rails with snap scrolling instead of a paginated grid
 *   - cards that expand on hover to reveal actions and metadata
 *   - a header that is transparent over the hero and solidifies on scroll
 *
 * Where wooary diverges deliberately: Netflix is a single-language-per-account product
 * and is built LTR-first. This theme is bidirectional throughout, which is why every
 * directional value below is a logical property.
