Picking the device's native mode on a phone hands the host the panel's own
aspect ratio, so the aspect-fit presenter fills every pixel — including the ones
behind the sensor housing and under the four rounded corners. That is why the
corners look cut off at max resolution while 1080p has always been fine: a 16:9
mode on a 20:9 phone pillarboxes, and those black bars land exactly on the
unsafe regions.
So the fix is entirely a sizing one — no layout change, no input change. Ask the
host for a mode narrowed by the unsafe inset and the existing aspect-fit centres
it inside the safe region; pointer mapping follows for free, because both
clients derive the picture rect from the live host mode rather than assuming
full-bleed.
Apple: `SafeDisplay` (PunktfunkShared, pure + unit-tested) and a "This device
(safe area)" row beside the native one, using Moonlight's formula — full native
height, width less the left+right safe insets. The stream is always landscape
but the settings screen may be portrait, where the same housing is reported on
`top` and the horizontal insets read zero; the portrait top inset stands in,
gated so an iPad's status bar never fabricates an inset.
Android: the same shape via `SafeArea` + a `SAFE_AREA_MODE` sentinel resolved at
connect like the existing `0`=native one. The cutout insets get the same
portrait fallback, and the rounded corners are added on top — Android does not
count them as cutout, and a full-height picture needs exactly the corner radius
of horizontal clearance.
Both even-floor and clamp, since `validate_dimensions` rejects odd dimensions
and an inset subtraction lands odd about half the time. Where a display has
neither cutout nor rounded corners the safe mode equals the native one, which on
Apple lets the existing dedup drop the duplicate row.
