/**
 * Amitry Project Showcase - Frontend styles
 *
 * Architecture:
 * - All sizing/spacing driven by CSS custom properties set inline by PHP
 * - Theme-resilient: every selector is namespaced under .apshow-showcase
 * - No `all: revert`, no `!important` unless explicitly required
 * - Container queries used where appropriate so grid responds to its own width
