fix(classmap): restore Spotify 1.3.0 controls and theme chrome

[afonsojramos]

Restore Spotify 1.3.0 toolbar sizing, theme container styling, and Settings toggles. The corrected map keeps module toolbar buttons at the native 32px size with 8px gaps, restores the shared navigation/player hooks, and hides the native checkbox behind its styled indicator.

Validation: 21 classmap tests, index integrity, and exposure-patch checks pass. Two recorded macOS runs captured all 14 Text/unthemed page states with no failed states, stable captures, and confirmed cleanup. Recorded pointer checks cover menus, toolbar/player actions, library controls, and Settings toggles.

Older-client coverage is archived CSS inspection, not a live run; Windows/Linux were not live-tested. No approved screenshot baseline exists yet. This PR publishes only runtime maps, metadata, and regression checks; the separate baseline proposal is not included.

Walkthrough

The 1030000 classmap artifacts add updated topbar, layout container, and settings toggle mappings. Metadata records related regression checks. New contract tests run in the index workflow, and index.json records the updated artifact hashes.

Changes

Classmap contract updates

Layer / File(s)	Summary
Update classmap and CSS mappings 1030000/classmap-19f856aefd5.json, 1030000/css-map.json	The topbar button uses the native class. Four CSS mappings cover three layout containers and the settings toggle.
Record regression checks 1030000/META.json	Metadata records four additional overlay entries and verification details for three regression check groups.
Validate contracts and promotion scripts/test_classmap_contracts.py, .github/workflows/index.yml, index.json	New tests validate staged mappings. The workflow runs the tests, and index.json stores updated artifact hashes.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to e6ec9

A valid later Spotify classmap can be blocked by the index workflow solely because its native topbar class differs from the 1.3.0 mapping. Scope the test before merging.
