fix(themes): restyle the player cover art on Spotify 1.3

[afonsojramos]

Summary

Spotify 1.3 dropped the main-nowPlayingWidget-coverArt wrapper around the player bar's cover art, so four themes stopped styling it. starry-night lost its large spinning disc, and the art fell back to a small square in the corner. turntable lost its record size and spin, dribbblish its cover size, and text its cover size when the cover is shown.

Theme fixes. Each rule that used the wrapper now also lists [data-testid="cover-art-button"] .cover-art. That test id exists only in the player bar, and test ids survive Spotify restyles better than hashed classes. The old selectors stay so builds back to 1.2.84 keep working. For starry-night, [data-testid="cover-art-button"] > div takes over the wrapper's sizing rule. Versions: starry-night 0.1.5, turntable 0.1.1, text 0.1.7, dribbblish 0.1.4.

spicetify/classmaps#25 also restores the old class name on 1.3.3 through the css-map overlay, which fixes third-party themes that use it. These theme changes additionally cover 1.3.0 and 1.3.1, whose hashes I could not verify.

Catching this next time. theme-report could not see this break:

• Pixel tracking skips starry-night because it animates.
• The binding check measures a whole theme's repaint share, which one dead rule barely moves.

The new selectors check fills that gap. Each run records which of each theme's selector parts match an element on each captured route, in current/selectors.json, which --accept keeps. The report lists every part that matched in the baseline, still exists in the theme, and now matches nothing on the same routes. Details:

• Parts are named after the theme's source CSS when the installed version matches the repo, because the css-map gives the served classes different hashes on every build.
• Interaction states and pseudo-elements are stripped before querying.
• Selector lists are split only on top-level commas.
• Unqueryable parts are counted, not silently dropped.
• A failed probe is recorded as a failure instead of aborting the run.
• If music was playing in one run and not the other, the report says so.

Accept a baseline on the previous Spotify build before a bump, and the first run on the new build names the rules that drifted.

Pinned playback. Every capture now shows the same track ("One More Time" by Daft Punk, overridable with --track), loaded muted and paused at 0:00. That keeps the playbar the same between runs, and selectors that depend on playback state no longer flip. Whatever was playing before, with its position, play state and mute, is restored afterwards, including when a capture fails.

Validation

• Live, on Spotify 1.3.3.264 (macOS arm64):
  • starry-night: the issue reproduced (56 px square art). With the fix the art is 220 px, round and spinning.
  • turntable: 62 px and rotating.
  • dribbblish: 40 px.
  • text: hides cover art by default (--display-coverart-image: none).
• theme-report, live:
  • With no baseline it reports "no baseline yet" instead of 0.
  • A partial run against a fuller baseline reports nothing lost.
  • With the baseline edited to look like a 1.2 run (old wrapper selectors matched), the 1.3.3 capture reports exactly the four broken starry-night rules.
• A live run showed the pinned track paused in the player, and the previous playback came back on the same track, at the same position, paused and unmuted.
• All 76 theme-report tests (1 skipped, as before) and the full suite (833 tests, 0 failures) pass. pnpm run check passes.

Closes #38

Summary by CodeRabbit

• Bug Fixes
  • Updated Dribbblish, Starry Night, Text, and Turntable themes to display cover art correctly with the player’s button-based cover-art layout. Starry Night and Turntable animations also work with this layout.

Walkthrough

The report now probes theme selectors during route capture and reports selectors that stopped matching compared with a saved baseline. Four themes extend cover-art styling to button-based markup and increment their metadata versions.

Changes

Selector diagnostics

Layer / File(s)	Summary
Selector probing and matching scripts/theme-report.ts, scripts/theme-report.test.mts	The report splits selector lists and probes normalized selectors against the DOM. Tests cover matching, nested commas, source selector names, and lost-selector conditions.
Route capture integration scripts/theme-report.ts	Live capture records per-theme, per-route selector results and playback state. The route tour probes the active theme after each route capture.
Baseline comparison and reporting scripts/theme-report.ts, scripts/theme-report.test.mts	Accepted baselines include selectors.json. The report compares shared routes and presents selector losses and playback-state differences in HTML, JSON, and console output. The acceptance test checks which files are copied to the next baseline.

Theme cover-art styling

Layer / File(s)	Summary
Button-based cover-art styling themes/*/index.css, themes/*/metadata.json	Dribbblish, starry-night, text, and turntable extend cover-art selectors to button-based markup. Each theme's metadata version increases by one patch version.

Full details: Out of Scope Changes check

Explanation

Issue [#38] concerns the starry-night theme. The PR also changes turntable, dribbblish, and text cover-art rules and metadata versions. It adds a general selector-reporting and baseline-comparison feature with tests. The linked issue does not establish requirements for those themes or for this reporting feature. These changes therefore exceed the scope established by [#38].

_{I’m a rabbit, hopping through the CSS,
I sniff out selectors that no longer match.
Button-borne cover art gets its place,
Spinning covers keep time in their track.
Baselines save the clues for next run,
Then I twitch my nose and call it done!}
