Three faults reported together, and they share a shape: each is something the
panel decided on the photographer's behalf.
**The column was 280px on every screen.** That width was chosen for a tablet,
where the column is a large fraction of the display and every pixel of it is
taken from the photograph. On a desktop window the mode strip alone — two
modes, a separator, "All", and a chip per attribute the operation set declares
— does not fit, so it scrolled sideways. A control you have to pan to reach is
one you do not know is there. 380px when the window is classed expanded, 280px
when it is not; driven off `layout-class` because reading the window width
inside the layout that sets it is a binding loop.
**The overlay could not be hidden.** An earlier "Overlay" button was removed
for a good reason — it *armed* the overlay, so local mode could be entered and
still show nothing. Hiding is the opposite need and was never served: a mask is
judged against the photograph beneath it, and that photograph is exactly what
the overlay covers. `overlay-hidden` is kept separate from `overlay-on` so a
recompute cannot switch the overlay back on under someone who just turned it
off.
**The masks were coarse because the model saw the subject small.** The graph's
input is a fixed 640x640 and every frame is letterboxed into it, so a bird
200px across in a 1600px proxy reaches the model at 80px. `Tiling::Grid` has
been implemented and tested since the segmentation spike and defaulted off,
because it costs one inference per tile — 2.8s for a 3x2 grid against 470ms.
Now offered as "Look closer (slower)", which says what it costs, rather than
spending it on every image or on none.
The tiling choice enters the segmentation signature. A mask stores the
signature its region ids index into, and a tiled run finds different instances
in a different order; sharing a signature would silently reinterpret a layer
built against the coarse pass — a wrong mask rather than a stale one, and
nothing announces it.
