* The icons the app draws, as glyphs in a Nerd Fonts subset rather than as vector assets.

* Drawing them as *text* is what makes them cheap: an icon beside a line of text wants that line's
* size, colour and baseline, and a `Text` gets all three for free where an `Icon` needs each one
* set and kept in step by hand.
*
* This replaced a hand-drawn canvas gear, whose doc comment argued against icon fonts on the
* grounds that a system font may not have the glyph and whoever gets the empty box instead is never
* the person who wrote it. That objection is about *relying* on a system font, and it is exactly
* right: the answer is not to avoid glyphs but to ship them. The font here is
* `app/build-icon-font.sh`'s output -- five glyphs, 1.4 KB, subset out of the 3 MB symbols font and
* committed -- so the codepoints below are resolved by an asset in the APK and cannot come back as
* tofu. Adding one means adding its codepoint in *both* places; a codepoint here that the script
* did not subset is a glyph that silently isn't there.
*
* The same arrangement as dev-updater, down to the cog and the refresh arrow being the same two
* Material Design codepoints. Those two must not drift: an icon that means "settings" in one app
* and something else in the other is the failure this is worth preventing. The script is copied
* rather than shared because most of what looks like duplication is the `GLYPHS` list, which has
* to differ -- the point of subsetting is to ship only the codepoints one app draws. All Material Design
