The playlist cards were showing "No description was pr…" because the API
stored that English sentence whenever a playlist was created without a
description. Descriptions are optional now and the old rows are cleared.
Section headings drop to 18/20px so they stop competing with the content,
and the space moved from inside the sections to between them.
The three media cards repeated the same anchor, art class and label
block, so they share a MediaCard that also carries the hover lift the
track tiles already had.
Every one of the seven tables repeated the same header markup and hand
written grid templates, always in the same shape: an optional index, the
title, optional desktop-only meta columns, the duration and an optional
action. TrackTable now takes that shape as props and builds both grid
templates and the headers itself.
A mix should read as one list, so the detail page drops the per-source
counters and the YouTube tag on each row, and the generated subtitles no
longer name Musify or YouTube Music.
Mixes are their own concept, not playlists: they live in their own
Mixes/MixItems tables, cannot be edited and never show up among the
user's playlists. Each item is either a Musify track or a YouTube Music
reference, so YouTube songs stream directly instead of being downloaded.
A daily Hangfire job seeds the mixes from the listening history: one
discovery mix, one daily mix and one per top artist.
The per-user YouTube filler query was already in the working tree and
rides along here because it shares files with this change.
