 The default playback setup requires **macOS 15+**, since Terebi is a native macOS player. Install Terebi separately and follow its dependency/setup instructions; installing Tubular does not install the player.

 Only episodes can have their watch status edited. Reopening a saved episode resolves new URLs; identity is the opaque Miruro catalog ID plus its returned episode number. Each interface shows only its provider's collections, while playback, watched state and storage remain shared. Episode markers show saved/watch-later/currently-watching membership and watched status; Terebi owns resume positions.
 
+Catalog results, series screens and saved-show lists use the returned `cover_url`; missing artwork leaves a text-only preview, and image failures do not hide metadata. Offline episode collections retain their stored text-only details. JPEG, PNG and WebP covers load, decode and resize off-thread, with native terminal graphics or proportional half-block rendering. The session image cache retains eight inactive images plus the current selection; a successful `r` refresh clears it.

 Stream and external VTT subtitle headers are supplied explicitly; Terebi selects the source's declared default subtitle. Sources requiring media redirects, cross-origin HLS, proxies, iframe playback, or provider-specific playlist rewriting fail explicitly. No provider/language fallback or automatic expired-source refresh is performed.
