Subject: [PATCH] artist page: five sections after the hero, and nothing moved
 to fit them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Latest release, Releases by year, Fans also like, In your library and
About slot into the page between what is already there — hero, Popular,
Discography grid and all — and CatalogArtist gains three lines: an import
and two placements. They live in ArtistExtras so Svelte scopes their
styles away from this file, which matters more than usual here: both
files name a .hero-bg and a .card, for completely different things.

Every section is fed by a call the app already makes. catalog_related is
Deezer's related-artists field, literally commented "Fans also like" and
simply never rendered on this page; the bio and profile calls already
run; latest and the timeline come out of page.albums. Nothing here needs
a provider that did not exist before. Latest release is CatalogSearch's
top-result hero — the app's only surface for presenting one item
prominently — with min-height 0 (there is no stat row to hold space for)
and a 6px artwork radius so it rounds like a record; it tints from its
OWN cover, scoped, so it never wears the playing track's colour. Fans
also like reuses this page's .grid/.release markup, so its columns are
the same 150px tracks as the discography above it, drifting 0px on all
six.

The release grid's min-height reserve had to learn about them. That
reserve is the tab-pinning contract — everything under the pinned tab bar
must span a pane-height — and when the grid was the last thing on the
page the grid had to supply all of it. It is not last any more, so both
reserves now discount the real content below it: without that the grid
stood on 206px of empty min-height under its final card, a hole nobody
could see until something rendered after it. The discount is
parent-bottom minus grid-bottom, which is invariant to the grid's own
min-height because both edges move with it, so the reserve converges
instead of chasing its own write; when nothing follows the grid it is 0
and the figure is exactly the old one. The grid's parent joins the
ResizeObserver, because the sections land asynchronously and grow it
without touching the grid's box or the pane's.

An earlier attempt pulled the sections up by a measured slack instead.
The grid reflowed after the measurement and they landed on top of the
release cards. Reverted: prefer a fix that can only be a few px wrong
over one that can be catastrophically wrong. Verified: expander open and
close leaves scrollTop at 1571, and the tab bar sits at 231 across
switches.

+     * inflation cancels out of the formula, so re-measures reproduce their own
+     * answers and stop.
