/* CBWatch shared design system.
 *
 * Extracted from what used to be duplicated <style> blocks in every page
 * (index.html, dashboard.html, compliance.html, ...) — each page kept
 * drifting slightly out of sync with the others because there was no
 * single source of truth for shared values. This file IS that source of
 * truth now: every page links it and then only defines page-specific
 * rules in its own <style> block (a scan-result card here, a domain-card
 * grid there) — never the shared tokens/components below.
 *
 * This is a refinement pass on the existing dark navy/teal identity, not
 * a rebrand — same --bg/--panel/--accent hex values as before, same IBM
 * Plex fonts. What changed: a real typographic + spacing scale instead of
 * ad hoc px values repeated with small inconsistencies across pages,
 * layered shadows/depth on panels instead of flat fills, a subtle
 * radial-glow page background instead of a flat one, and consistent
 * hover/interaction treatment on buttons and cards.
