/* defuss-shadcn - optional accessibility utilities.
 * Text meant for assistive technology only (.sr-only) and its inverse
 * (.not-sr-only). The clip pattern keeps content in the AT tree while
 * removing it visually - display:none would hide it from screen readers too.
 * Focusable elements re-reveal via :focus / :focus-within so keyboard users
 * never lose the control entirely (the Tailwind idiom, kept intact).
