/* window.css — additive styles for the in-page window manager (window.js).
 *
 * Reuses shared common-web classes wherever possible:
 *   .card               — the window frame (background, border, radius, padding)
 *   .fs-title           — the sticky header bar (font, spacing, sticky top)
 *   .err-close          — the ✕ button (matches fullscreen + toast close)
 *   .fs-active          — the MAXIMIZED state (inset: 0, backdrop shadow)
 *
 * Only bits that don't have a shared equivalent live here:
 *   - Fixed-position + drag origin
 *   - Minimize/maximize buttons (fs-trigger sized, not styled elsewhere)
 *   - Taskbar strip for minimised windows
