leviath-cli 0.3.8

//! Color palette, glyph constants, and spinner frames shared by every Leviath
//! terminal UI (`lev dash`, the `lev setup` wizard, and the markdown renderer).
//!
//! This is the single definition: `commands/dashboard/theme` is an alias of
//! this module and `render.rs` imports from here, rather than each surface
//! carrying its own hand-copied palette. Two surfaces drifting apart is a real
//! cost the moment a third one exists.
