kazari (飾り)

The line-output face of the fleet. Typed, capability-honest, dark-Nord / blackmatter beautiful CLI output — banners, callouts, panels, rules, lists, badges (tables / trees / progress / diagnostics at M2) — as a pure-data, format!()-free Block IR.

kazari is the sibling of seki: seki dresses the prompt (before the command), kazari dresses the output (after the command), over the one ishou / irodori token spine that also feeds egaku-term (the cell-grid) and tela (the web). Four faces, one spine.

A Block carries no color depth. render() requires a Capability supplied by the environment — so "assumed truecolor on a pipe" is a compile-shaped absence, not a runtime clamp. The same value degrades truecolor → 256 → 16 → NO_COLOR through one total morphism.

use kazari::prelude::*;

banner("sui — Rust-native Nix").print()?;          // rounded box, Frost accent
ok("realised /nix/store/…-hello (byte-parity)").print()?;   // ✓ Aurora green
warn("cache miss — rebuilding").print()?;          // ⚠ Aurora orange
error("exit 1").with_title("build").eprint()?;     // ✗ Aurora red

Panel::titled("store")
    .row("path", "/nix/store/…")
    .row("closure-size", "42 MiB")
    .print()?;

Piped or under NO_COLOR, the same code emits zero escape bytes and a plain [TAG] / ASCII-glyph projection.

• OWNS (the ~15% genuinely-new, 0-hit fleet gap): the ColorLevel capability wall, the RGB→256→16 nearest-in-linear quantizer, the line-block AST.
• CONSUMES irodori (Nord palette, no fork) · WRAPS anstyle (typed SGR — the escape bytes are anstyle's, never hand-spelled).

Dark-Nord by default (fully morphable). Design + tier-honest ledger: theory/KAZARI.md.
