/**
 * PageSkeleton — pixel-perfect loading skeletons that EXACTLY match each page's
 * actual DOM structure.
 *
 * KEY PRINCIPLE: When the real content loads and replaces the skeleton, there
 * must be ZERO layout shift. Every skeleton block has the same width, height,
 * padding, margin, border-radius, and position as its real counterpart.
 *
 * The shimmer class is defined in globals.css.
