First increment of the artist-detail unification redesign. Delivers
the two most-visible missing pieces for source artists without touching
the hero layout — that's a later commit.
Changes:
- HTML: new #ad-similar-artists-section inside #artist-detail-main
(scoped IDs with 'ad-' prefix so they don't collide with the inline
Artists page, which has the same section using base IDs).
- shared-helpers.js: similar-artists helpers (loadSimilarArtists +
display/progressive/createBubble + lazy image loader) moved out of
artists.js. New _resolveSimilarArtistsTargets() resolver picks
whichever candidate set has a `.page.active` ancestor, so the same
function works on both the inline Artists page and the standalone
artist-detail page without caller changes.
- library.js populateArtistDetailPage: sets
document.body.dataset.artistSource = 'library' | 'source' before
rendering, and fires loadSimilarArtists(artist.name) after
populating the rest of the page.
- style.css: body[data-artist-source='source'] rules hide
library-only UI on the artist-detail page — Enhanced view toggle,
Status (owned/missing) filter, completion bars, enrichment
coverage, Top Tracks sidebar, Radio / Enhance Quality buttons,
"X owned / Y missing" section-stats counts. CSS-only, additive,
library artists completely unaffected.
Impact today:
- Library artists: Similar Artists section now appears at the
bottom of their detail page (previously only the inline Artists
page had it). All other UI unchanged.
- Source artists: still route to the inline Artists page (Part B
reverted earlier this session). The standalone page is now
source-ready infrastructure-wise, but source artists don't reach
it yet. A later commit will re-migrate source callers to the
standalone page once the hero rendering is also source-ready.
artists.js shrinks from 1903 -> 1584 lines (similar-artists block
extracted). shared-helpers.js grows correspondingly. 357/357 tests
still pass. No version bump — this is still 2.39 pending.
