"""Render profile/README.md from profile/README.template.md in any of the 9
palettes that ghostlabs.web.app ships in its Tweaks panel.

    python3 generate.py              # list palettes + show the active one
    python3 generate.py phosphor     # re-skin the README to "Phosphor CRT"
    python3 generate.py bone         # light-mode "Bone & Ink", etc.

The palette values mirror the site's PALETTES map (signal.jsx). Each token is a
hex string WITHOUT the leading '#', because that's the form the badge/render
services (shields.io, capsule-render, github-readme-stats) expect in URLs.
