/*
 * Cobalt design system for PowerPointer's Blazor Server front-end.
 *
 * Ported faithfully from the static mockups' <style> blocks:
 *   - docs/ux/mockups/components.html (the UI Kit — component states in isolation)
 *   - docs/ux/mockups/screens.html    (the composed app shell + chrome)
 *
 * Class names are kept IDENTICAL to the mockups so the Blazor port is a mechanical
 * 1:1 of the design. This stylesheet is the single source of truth for app chrome.
