/**
 * Animations CSS - Entrance and interaction animations
 *
 * CASCADE-LAYER DISPOSITION (D9-06): animations.css declares `array('rhuarcs-style')`
 * as a wp_enqueue dependency, so it loads AFTER style.css. Its `.animate-spin`,
 * `.animate-pulse` and `.animate-bounce` utilities exactly collide with the same
 * UNLAYERED classes in utilities.css (the after-loading pair, layered in 09).
 * Layering this sheet while those competitors stay unlayered would let utilities.css
 * win (unlayered beats @layer) — a cascade regression. The animation utilities here
 * form one cohesive cohort coupled to those collisions, so the sheet is kept
 * UNLAYERED and reconciles in the atomic Plan 09-09 (style.css/utilities.css
 * co-layer). The 4 `!important` are reduced-motion guards (base.css:306 shape),
 * documented survivors (D9-07d).
