/* allmeta — Windows High Contrast / forced-colors mode (WCAG 1.4.1, 1.4.11).
 *
 * Each app self-styles, so OS-supplied palette tokens (Canvas, CanvasText,
 * ButtonText, LinkText, Highlight, VisitedText) are forced over our custom
 * variables when forced-colors is active. We surrender our color palette so
 * the OS contrast contract wins, but we keep our structural CSS.
 *
 * Apps with custom-colored decorative svg/canvas plots should add their own
 * targeted overrides — this file establishes baseline survivability only.
