The UI runs on Arduino's loop task, whose stock 8 KB stack had 340 B left
at its deepest point; a screenshot's file write went past it and reset the
device. The loop stack is now 16 KB (measured peak ~7.8 KB) and the
screenshot's line buffer is static. Diagnostics names the row
"UI stack free (lowest)".
With a cable in at boot, the USB popup waited for nothing and showed over
the splash; it now comes once the splash has faded.
Adds docs/development/plan-next.md, the plan up to the merge into dev.

"solo", our version, upstream's and the build date (as digits) are drawn
in the wordmark's letters, the missing ones (l, v, d, digits, '.', '-')
made to match; a line with any other character falls back to Noto.

- Anim.h: screens emerge from the middle (background cover fades, content
drifts 6 px), Home pages slide, popups and toasts rise and fade in
- Theme.h: accent rules (fill = primary action, dim fill = selected, text =
names/counts/modes), theme layer over the default theme, radius tokens,
accent colour picker (Settings > Display & power > LOOK, NVS mc_ui)
- Splash with the Solo and upstream versions
- Status icons in equal cells, L1-style relay marks, path window with a hop
diagram, tile download popup fits the screen (WiFi only in Settings)
- Perf: uncompressed fonts, two 120-line PSRAM buffers (~48 -> ~33 ms per
transition frame); UI_PERF_TEST harness
