/*
 * Android Platform R8 Configuration Analyzer — dashboard styles
 *
 * Organized in the same order as the rendered DOM, top to bottom:
 *   1. Design tokens (CSS custom properties)
 *   2. Base resets and element defaults
 *   3. Header (branding, toolbar, sub-toolbar)
 *   4. Main layout primitives (stacks, cards)
 *   5. System view (platform totals, axis panels, offenders, system rules, scoring policy)
 *   6. View intro (page heading shared by Builds + Rules views)
 *   7. Builds table (head, rows, expansion)
 *   8. Rules table
 *   9. Empty / overflow states
 *
 * Naming: BEM-ish — block names use the section prefix (`axis-`, `builds-`, `rules-`,
 * `sys-rules-`), modifiers use `.active` / `.open`. CSS custom properties live on :root
 * so theme tweaks happen in one place.
