Under the ambient field some controls still painted the opaque theme
token while their neighbours used the half-alpha one: the album track
filter and its select toggle, the Library tab strip's host, the Local
Library icon selects, the header's active nav items and open playlists
button, the queue sidebar's now-playing card and artwork placeholders,
the Listen list's floating actions, and the shared SettingsButton,
IconTextButton, multi-select bar, text area, load-more pill, tree row
selection, sidebar count chips, Purchases tab strip, play-history filter
box and Orbit banner. Each now takes the ambient-aware fill the header
search and QbzTabBar already use (theme.ambientOn ? …A50 : …).
Tooltips, popups and modals stay opaque on purpose: they are read over
content, not chrome.

Five hand-rolled "Load more" buttons existed in three visually distinct
shapes. One control now carries all three arms, so the idle appearance of
every site is unchanged. While a fetch is in flight it draws a QbzSkeleton
composite BELOW the button - the owner asked for below - which is one
animator for the whole placeholder row, with settleMs 8000 so a fetch that
never returns stops shimmering instead of pulsing forever. Idle it costs
nothing: the block lives behind an inactive Loader, so mounting the control
changes no pixel on a page nobody has clicked.
SearchView had half of this already, and the half it had was on the wrong
side: a skeleton ABOVE the button, on the albums tab only. All four tabs now
use the control, each with its own real cell pitch and row shape rather than
the albums tab's numbers copied across.
AlbumCollection gains an opt-in tail fade (armTailFade) for the arrival half
of the round. It is keyed by the set of ids on screen at click time, not by
an index threshold: the label page sorts its grid, and under any order but
newest a fetched page interleaves, so a threshold would re-fade albums that
never moved - the flicker the fade exists to avoid. It also lets grouped mode
fade, where there is no flat index at all. Inert unless a host arms it, so
Discover Browse and Play History are bit-for-bit unchanged.
