/*
 * Cybytez Portfolio — PHP public site stylesheet.
 *
 * Sections 1-6 are copied verbatim (values, not structure) from the Astro
 * site's src/styles/*.css — the authoritative design tokens/reset/type
 * scale/utilities. Section 7 flattens the Astro components' scoped
 * <style> blocks (Header, Footer, MobileNavigation, Container, Section,
 * Button, ActionLink, Badge, SectionHeading, SocialLinks) into plain
 * global selectors — Astro's per-component CSS scoping has no equivalent
 * need here since these class names are only ever emitted by this
 * stylesheet's own PHP templates. Section 8 is new: card/hero/grid
 * patterns for page sections, built from the same tokens rather than
 * transcribed from Astro (see php/README.md for why).
