/**
 * SHARED PAGE LAYOUT
 * ===================
 * Content layout styles for subpages (bio, donate, etc.).
 * Base resets, body, noise, and header are in base-page.css.
 * Each page provides a container class and may override
 * --page-glow-color / --page-glow-subtle if needed.
 *
 * STRUCTURE (ITCSS):
 * - Settings: Glow custom properties
 * - Components: Subpage container, page heading, page section, photo with glow
 * - Utilities: Shared animations
 * - Overrides: Media queries, reduced motion
 *
 * BEM NAMING:
 * - Blocks: .subpage, .page-photo
