The sidebar source-group headers (Spotify / Tidal / Qobuz / Deezer /
YouTube / Last.fm Radio / ListenBrainz / iTunes Link / SoulSync
Discovery / Spotify Link) only showed the source name in caps —
the dashboard equalizer + connections panels both render the
actual brand logo, so the sidebar reading as text-only felt
disconnected.
Added a small (18px) circular brand-logo chip to the left of
each source-group title, sourced from the same URLs the
dashboard equalizer avatars use. Dark glass backdrop + accent
ring + drop-shadow on the logo so the chip stays legible
against either light or dark marks; brightness(0) invert(1)
applied to Tidal / Qobuz / iTunes-Link so their dark-foreground
marks render as white silhouettes against the disc (same
recipe the equalizer overrides use). Last.fm's square avatar
PNG clips to a circle via object-fit: cover.
Sources without a publicly available logo (Beatport, file
imports) fall through to no-chip — the <img onerror> swap
hides the broken image so the header still renders cleanly.
