An App in the Launcher that runs the same commands as USB serial and the
Debug Console, trusted like the first. It shows what the console prints
while it is open, through a second ring of the console's that exists only
meanwhile; Ctrl+b keeps only what follows your own commands. Tab completes
a command's name from the firmware's help text, Fn with up and down recalls
earlier lines, Alt with up and down scrolls back. `rm` asks first in the
Shell, `rm -f` doesn't. Nothing is kept once the App is left.
`screenshot [seconds]` saves the screen as a PNG in /screenshots on the
card, now or after a pause: written a row at a time, indexed colour with
RGB332 as the palette, in one stored deflate block.
487 host tests (11 new: the PNG writer, the Shell's log filter, Tab).
Checked on the device over the Debug Console: commands, Tab, history, a
screenshot fetched and decoded on the PC, rm with and without the question,
a delayed screenshot of another screen. 12 KB of flash; 7 KB of heap while
open. Decisions Q204 to Q212 in docs/milestones/S1.md. Safe Mode: #77.

Every screen's keys are constant tables in lib/core/src/app_keys.h (52 of
them, each under an `// id: Title` comment). An App's help() picks the table
of the state it is in. site/tools/gen_dev_docs.py reads the same file and
writes site/data/keys.toml; the `keys` shortcode shows a screen's tables on
its guide page, and /guide/keys/ shows all of them.
The Site job fails when the data file is out of date or a page asks for a
table that doesn't exist, and now also runs when app_keys.h changes. A key
added to an App shows up on the website without anyone editing a page.
