Ships catppuccin-mocha (faithful to the official Catppuccin Mocha
palette) and catppuccin-mocha-hc (high-contrast sibling per D-69 — the
faithful palette is never retuned to pass the gate). Both bundled and
gated: mocha clears baseline AA, mocha-hc clears the strict extended
set. Catppuccin MIT palette recorded in licenses.yaml.
Closes T-82 (Mocha + hc meets every acceptance bullet; faithful Latte
deferred — it can't clear baseline AA without retuning, a separate call).
