 * Module: CTA Variant Composition Layer
 * Target: src/core_apps/frontend/static/frontend/themes/_shared/sections/cta/cta-variants.css

 *   split   → Brand-colored background, side-by-side text + button, diagonal accent
 *   boxed   → Gradient floating card with elevated shadow, centered content
 *
 * Specifications (HMS-Grade):
 * - Rule A: Zero sibling positional dependence
 * - Rule B: Rigid Static Weight Budget (Limit: 10 KB uncompressed)
 * - Rule C: Absolute scoping containment
