/* Song link sharing panel (Library song detail "Share to Facebook").
 *
 * Uses the existing `--pt-*` design tokens (web/styles.css's "PorchTunes
 * Design System — Phase 4" block) with safe literal fallbacks, so this
 * file renders sensibly even before a maintainer links it from
 * index.html. Never redefines a `--pt-*` token — reads only, matching
 * DESIGN_TOKENS.md's rule that token values are hand-synced from one
 * canonical place.
 *
 * Accessibility: focus-visible outlines are not suppressed anywhere in
 * this file; the disabled Share button keeps a visible outline on
 * focus (a disabled native <button> is skipped by tab order by the
 * browser itself, so this matters mainly for the enabled state);
 * `prefers-reduced-motion` disables the one transition used
 * (background/opacity fades only — nothing here relies on motion to
 * convey information).
