Rates are saved per display (EDID ID) and loaded by the hotplug script
for whichever display is connected. The item is on only while the
connected display is boosted; unticking removes just that one. The app
lists the saved displays and removes any of them (hdmi-forget).
Set up… opens a screen with the display, its resolution and the rates on
offer. The display's own faster mode is switched to right away; the other
rates can each be tried live (wait for the picture, keep within 15 s or it
switches back) and ticked; Install installs the ticked ones through
apply --hdmi. All rates are loaded when the screen opens, so a try is only a
mode switch. Also fixes switching back to a rate like 59.97 Hz.
The app gets its texts and the same rules as the menu: unticking Steam
Machine support or the kernel pin unticks it. It can't be turned on from
the app, as each step needs someone at the keyboard to confirm the picture.
bios_enable split into bios_prepare (download, checksum, fwupd check) and
bios_flash; the terminal flow is unchanged. The app: check, warning 1,
warning 2 (type UPDATE, or hold A/OK for 5 seconds), flash, restart.
ui/steamify-ui (PySide6 + QML): menu, review, password, applying and done
screens from the design, scaled to the window. Controller via evdev,
keyboard, TV remote (cecd). steamify.sh --backend status|apply (lib/backend.sh)
drives the same components; sudo asks through an askpass helper.
