/*
 * Something Pithy — direction
 *
 * A clearing at dusk. Dark, warm ground; moss and lichen for anything alive; one ember
 * for the things that need care — recording, clipping, deleting. Nature is in the palette
 * and the softness, not in the decoration: no leaf borders, no wood-grain images, one fir
 * in the favicon and that is the lot. The reason is practical as much as aesthetic — the
 * meters and waveforms are the loudest thing on the screen, and they only read that way
 * on a quiet ground.
 *
 * Dark only, declared rather than defaulted. This gets used in the evening, and every
 * canvas in the app is drawn for a dark ground; a light variant would be a second set of
 * colours to keep the meters legible in, for no gain.
 *
 * Canvas colours are read from the custom properties below via getComputedStyle, so the
 * palette lives here and nowhere else. Renaming one means updating readPalette() in
 * assets/studio/meters.js.
