/*
 * TagGenius AI - YouTube Title Generator
 * Frontend styles. Fully scoped under .tgai-ytt-wrapper — never touches
 * global selectors (body, button, input, h1-h3, etc.) so it cannot break
 * Astra, Elementor, Gutenberg, or other TagGenius AI tools on the page.
 *
 * Colors are defined as CSS custom properties scoped to the wrapper so
 * they automatically inherit Astra's active theme palette where available,
 * and fall back to the TagGenius AI blue/red brand combo otherwise.
