 * TG Bridge panel — one stylesheet, no build step, no external fonts.
 *
 * No webfont on purpose: the bridge is deployed outside Iran and read from
 * inside it, and a Google Fonts request is one more thing that can be blocked
 * or slow. The system stack renders Persian correctly on every platform this
 * panel is opened from.
