// Mocha palette: Catppuccin Mocha ground, blue as the accent, pink as the
// alarm. Persona geometry, softer colour.
//
// The Takemi branch ran monochrome-plus-crimson, where one hue carried both
// "active" and "wrong". Mocha has room for two: blue is every resting accent —
// focus, selection, the thing you are pointing at — and mauve is reserved for
// the things that bite, so destructive and error still read at a glance
// without a third colour entering the shell.
//
// Mauve rather than Mocha's pink: pink is a pastel, and a slab of it over this
// ground goes chalky. Mauve is saturated enough to hold an edge against the
// near-black surfaces the Persona layout is built from.
//
// Everything else is Mocha's own neutral ramp. Fills stay flat and keylines
// stay hard; only the hues moved.
