 * Talos Foundation CSS
 *
 * Canonical brand-token and component foundation for Talos digital pages.
 * Implementation layer of Talos Brand Memory.
 * Organized in layers:
 *
 *   1. Tokens          — colors, typography, surfaces, borders, accents
 *   2. Base            — reset, body, page shell
 *   3. Typography      — semantic type roles
 *   4. Core            — panels, pills, chips, dots, green-line, tabs, legends, tooltips
 *   5. Content         — mastheads, masthead hero, key metrics (kpi-*), view headers, compare cards, footers
 *   6. Structured data — matrices, timelines, pipelines
 *   7. Diagrams        — architecture trees, process flows
 *   8. Responsive      — breakpoint overrides
