/**
 * tones.ts, the canonical UI tone-token table, hoisted from `goodvibes-tui`
 * src/renderer/ui-primitives.ts (UI_TONES + DIFF_TONES + SPINNER_FRAMES) and
 * src/renderer/theme.ts (resolveUiTones / UI_TONES_LIGHT).
 *
 * TONE_TOKENS mirrors the TUI's UI_TONES shape byte-for-byte (the TUI is the
 * reference, and its dark values are the accepted baseline, this keeps a
 * future TUI swap onto this module a no-op). resolveTones(mode) is the single
 * mode-resolved read path: 'dark' returns TONE_TOKENS itself (so a byte-identity
 * check against the constant is trivially true), 'light' returns the inverted
 * chrome/accent variant tuned for legibility on a light terminal background.
 *
 * This module is PURE data, no fs, no terminal I/O, no process globals.
 * Painting stays renderer-owned; this module owns only the token values and
 * the mode-resolution function.
