/* AudioSilo admin/connect UI. Design cues are ported from the Expo player
   (~/dev/audiosilo-frontend): Roboto, dark-mode-first, borders-instead-of-shadows.
   The accent is Tailwind violet (#7c3aed) - deliberately distinct from the player's
   pink (#db2777) so the admin console reads as a different surface at a glance.
   The pages are served under a strict same-origin CSP (style-src 'self';
   script-src 'self'), so ALL styling lives here - there are no inline <style>
   blocks or style="" attributes in the HTML. */
