What each kind of screen gets. Solo has two UIs: ui-new (buttons, every
board but the L2) and ui-lvgl (touch, the Wio Tracker L2). Within ui-new,
some content depends on the screen's size and kind, the rest on the hardware
(build flags).
Keep this up to date: a change that adds a feature to only one UI, or only
to some screens, adds or corrects its row here in the same commit.

Gaps
Things one side has that the other could:
- L2 → ui-new: history on an SD card (no card on the L1); a base map
under the trail and the nodes (no card either, but the L1 has 2 MB of QSPI
flash: a lite vector pack is being measured).
- ui-new → L2: T9 layout; CardKB; GPIO on the Grove port; the magnetic
cover (no sensor).
- Small screens: the e-ink charts (RAM: 8 h of history).
