The PicoCalc draws its path lines as chips

The console font gains the two powerline chevrons, drawn into the next
two donor slots (U+2559 and U+255B, which nothing draws), in both the
6x12 and the 6x8 builds. With them in its inventory, the PicoCalc's
verdict is core, so its routes are ribbons of chips like the
Cardputer's.

A chip there can only be filled from the eight background slots, since
under a 512-glyph font the VT has no bright backgrounds. So a node's
chip is the dim twin of its hue (theme.DIM_TWIN), and its label is the
hue itself: the colour the name has in every list and in arrow mode. A
hash label and an annotation are that colour throughout. A keyless chip
is white on light grey, the same pair one bank down. Our star, a faded
hop and the composer's slot have no dark grey to stand on, so they
stand on the page, the slot as a white + in a break of the ribbon. Two
chips of one colour join on a thin chevron in that colour.

Bold is brightness on the console, and Rich merges a selected row's
bold into every span on it, which turned the dim fills bright. Every
chip style there says "not bold"; the tests read the rendered row back
through the emulator's VT to hold that.

The new font takes effect once the font script runs again on the Lyra
(as root). Until then the PicoCalc's installed font lacks the chevrons.
