Block B2 of the miniplayer/tray contract, and the block that settles the
premise the whole port rests on: a second top-level Window in the same
QQmlApplicationEngine reads the SAME bridge singletons as the shell. Proven
by driving it — a probe window with one Text bound to QbzPlayer.npTitle
tracked the main window across a track change with no mirror code. Slint
needs ~155 lines of mirroring for this; Qt needs none.
qml/miniplayer/ (new, six files) — MiniWindow (frameless, transparent,
transientParent null, its own key host and its own onClosing), MiniShell (the
card, the artwork backdrop, the surface router), MiniCoverArt and
MiniExplicitBadge (the two components MiniBits.slint exports, which cannot
share one .qml file), and the compact and artwork surfaces.
The card is the window minus a 6 px gutter, its radius is 9 for the condensed
surfaces and 10 otherwise, and switching the surface RESIZES THE WINDOW —
540 to 178 and back, driven and measured, not inferred.
The backdrop lives inside a masked container. `clip: true` on a rounded
Rectangle does NOT round its children on this Qt build — theme/RoundedImage.qml
records that as measured fact — so without the mask the scrim and the
atmosphere's own opaque root would paint square corners over the card the
moment the backdrop is on. That is reachable before its toggle exists,
because the pref is co-owned with the shipping Slint app.
src/mini_bridge.rs — enter/exit, the mini's own key dispatcher, and toggle().
Re-entering an open mini re-raises it rather than doing nothing, which is
what the reference does and what present() will want.
src/hotkeys_qt.rs — action_for_mini_key, a SIBLING of action_for_key with the
context arm inverted. The main window still refuses Context::Mini and the
test that pins it is untouched; a new test pins the mirror.
src/hotkeys_bridge.rs — the ui.miniPlayer arm stops logging and toggles.
qml/shell/ViewModeMenu.qml — the Miniplayer row goes live with its own
dispatch arm, and it is hidden under the kiosk profile, 1:1 with
PlayerBarSmall.slint:819. The kiosk port landed first, so that gate was owed
here. Three comments claiming the row is inert are corrected.
Surfaces 0, 3 and 4 are clamped to the artwork surface until their content
exists (B3 and B4), because mini_surface and mini_default_view live in the
prefs file shared with the Slint app: a user whose Slint mini was last on
Queue would otherwise open onto a blank card with no visible way out. Each
block deletes its own entry from that clamp.
Enter does not hide the main window yet — window.hideToTray() is B6's, and
open-coding a bare hide() here is what the one-visibility-owner rule forbids.
So the main window stays visible behind the mini in this commit, by design.
