Four things from the owner's smoke, all polish, all measured on real Plasma
Wayland rather than inferred.
ALWAYS-ON-TOP IS GONE. It shipped as owner ruling K1's default — new work
the reference promises in three comments and implements nowhere — and it does
not work: a Wayland client cannot raise itself above other clients. There is
no such request in the core protocol; it takes a compositor policy or a KWin
rule, and Qt has nothing to send. The owner's call was explicit, so the
button, the property, the invokable and the pref are all removed rather than
left as a control that lies. The capsule is nine buttons again.
THE MINI'S SIZE IS NOW FIXED PER SURFACE, min == max. A Plasma tiling
shortcut resized the mini to half the screen, the debounced persist wrote
1720 px into the shared ui_prefs.json, and every expanded surface opened
giant from then on — with no way back, because this port never gave the mini
a resize handle. So the only thing that could ever write those prefs was the
window manager, i.e. the bug. The owner asked for exactly this: force the
sizes even when the OS says otherwise, stay sensitive to position. min == max
gives both — a compositor may still move the window; a resize is refused.
That drops the reference's resizable expanded mini and the persisted pair
with it (A-6b / AC-15). `saveGeometry` and `geometry_to_persist` stay, with
UT-3: they are the right rule for the day a real resize handle exists, and
deleting a tested guard to re-derive it later is how this comes back.
The micro capsule now centres on the CARD, not on its 17 px header. The
reference centres it on the header, but in micro that header is a strip at
the top of a 45 px card while the capsule is 26 px tall, so it sat visibly
high.
A SEEK NOW REPORTS ITS NEW POSITION TO MPRIS. Position was only refreshed on
the play/pause edge, so a desktop widget extrapolated from a base the seek
had invalidated — the owner measured ~40 s of lag. The shared crate exposes
no Seeked emitter and set_playback already carries a position, so the seek
re-asserts the state at its target. The shipping Slint build has the same
gap; closing it there is a shared-crate conversation, not this one.
Not fixed, and it cannot be here: the mini does not remember its POSITION.
Wayland gives a client no way to place itself. Contract ruling K4 said so;
the owner's session confirms it. It would work on X11.

The owner photographed it against a white background: every mini surface
rounded on top and SQUARE at the bottom, and the micro card — the smallest
of them — square on all four. Their read was right: "los NPB son cuadrados
y no tienen transparencia, así que aunque el fondo tenga esquinas
redondeadas, el npb prevalece".
The footer is an opaque Rectangle anchored to the card's bottom edge, and
the card cannot round it: QML's clip is RECTANGULAR. theme/RoundedImage.qml
records that as measured fact on this Qt build — "the child paints square
over the rounded fill" — which is the same reason the artwork backdrop
needed a mask two commits ago.
So the footer rounds its own corners, with per-corner radii (Qt 6.7+; this
tree builds against 6.11): the bottom two in every mode, and all four in
micro, where the footer IS the whole card. That last case is exactly why the
smallest surface was the one with no rounding at all.

Block B3. The owner's verdict on the four blocks that landed before it was
that the miniplayer was "no draggeable, no hay controles de ningun tipo. Ni
de reproducción, ni para cambiar entre modos, no es pinneable." All of that
lived here.
qml/miniplayer/ — MiniFooter with its three modes, and the five primitives
the reference declares as inner components: MiniSeek, MiniTransport,
MiniVolume, TBtn and CapBtn, one file each because a 396-line Slint footer
folded into one QML file lands well past the size rule. MiniWindowControls
is the hover capsule: five surface tabs, a separator, then expand, pin,
backdrop, drag and close, plus the collapsed square trigger.
The transport in full and compact is centred by a PHANTOM SPACER the width
of the volume button, not by a centred layout — micro has no volume and is
the one mode genuinely centred. The seek carries the reference's pending
machine: the -1.0 sentinel, the 0.02 convergence window and the 8s watchdog.
The capsule is a conditional MOUNT, so leaving the card destroys its
expanded flag and its 250ms timer with it.
ALWAYS-ON-TOP is new work, not a port: three comments in the Slint tree
promise it and no code implements it. The owner asked for it back because
Tauri had it and Slint structurally cannot. Qt.WindowStaysOnTopHint, a pin
button, and a persisted pref that defaults ON.
COLOUR LITERALS: six were carried over from the reference verbatim and every
one of them was WRONG. Slint writes #RRGGBBAA; Qt parses #AARRGGBB, so
#ffffff33 is not white at 20% but opaque pale yellow — which is exactly how
the capsule rendered until it was driven and looked at. This is the second
time this trap has landed in this port. Each converted literal now carries
the reference form beside it. One of the six is MiniShell's, from B2.
mini_qt.rs — surface 0 leaves the temporary clamp, because the micro footer
IS the card and now exists. Surfaces 3 and 4 stay clamped until B4.
Driven and seen, not inferred: the footer in artwork and micro, the capsule
revealing on hover and collapsing on leave, the micro card at 380x57 with
its centred transport, and the pin persisting mini_always_on_top across a
toggle. The drag handle is wired to startSystemMove on pressed; the VNC
platform cannot move a window, so that one is owed a real compositor.
