/*
 * Letter Desk (owner only). Palette and type come from /css/tokens.css and the base
 * controls from /css/site.css. The four level colours below are local to the desk:
 * every level also carries a word and a symbol, so colour is never the only signal.
 * Contrast of the words on their fills: red 7.3:1, amber 6.5:1, green 9.6:1, note 5.0:1.
