/*
 * Lobby Studio — admin view styles.
 *
 * Reskinned onto the admin design system,
 * sibling to the Layouts → Login tab. Token-driven light-content styling, all
 * scoped under `.main` / `lobby-*` so nothing leaks into other sections. Gold
 * (`--color-accent`) is reserved for the primary Save action, the active
 * selection accent, and focus rings only.
 *
 * The legacy `.modal--card` / `.modal-backdrop` / `.snippet-box` / `.modal__*`
 * block at the BOTTOM is SHARED with `views/history.js` (its embed + filter
 * dialogs consume these classes). It is intentionally left as-is — do not
 * restyle it here; history is polished in its own pass.
