Validate on c93b3a90 failed no-new-private-writes: the smoke moved the
camera by writing card._view. It now presses the header zoom buttons
(data-hp zoom-fit / zoom-in) until the label font has at least doubled
(14 -> 38 px on the demo stand) and reads the private camera state only to
wait for the transition. Same assertions; the mutant
iso-room-label-44-box-centres-name still turns it red
(gapMatchesFlatAtEveryZoom, gapIsZoomIndependent).

The raised room label in 2.5D View sized its own box to the 44 px touch
minimum (min-height + justify-content: center). The name therefore sat
centred in 44 px while the metrics row, placed absolutely from the label
bottom, hung (44 - name height) / 2 below it: 18.3 px at a 9 px name and
6.4 px at a 39 px one on the demo stand, against a constant 0.1 name
height on the flat plan.
The 44 x 44 px floor moves into an invisible ::before (the door-lock
pattern), z-index -1 inside the label stacking context; the label box is
sized by its text again.
demo/smoke_iso_room_label_metrics.mjs measures gap / name height at two
cameras (font x4) in Flat and 2.5D, and the 44 px floor and area-link hit
targets on labels no raised device covers. Mutant
