                                # Theme.ps1 — design tokens shared by the TUI (Spectre markup names) and the

# startup report (raw 256-colour escapes). One source of truth: the UI layer

# (src/UI/00-Theme.ps1) reads its palette from here, and the report renders

# the same tokens without Spectre being loaded at profile time.

# Markup names verified against the Spectre.Console colour table; Index is

# the matching xterm-256 number the escape sequences use.

# Theme knob: $PSMM_Theme = 'glacier' | 'ember' | 'moss', set in $PROFILE

# before Import-Module psmm. Unknown values fall back to glacier; the UI

# shows a one-line status note (Test-PSMMThemeFallback).
