/*
 * Tailwind config for static/v3/plugin-frame.css: the stylesheet
 * /v3/plugin-ui/<plugin>/web-ui/<file> links for a plugin's web_ui/ fragment
 * (shown in an iframe on the plugin's config tab).
 *
 * Fragments used to load Tailwind v2.2.19 from a CDN, which fails when the Pi
 * is in AP mode with no internet. Their markup lives in plugin repos and
 * can't be scanned here, so instead of content globs this file safelists the
 * common utility families at the values the v2 CDN had. A fragment that
 * needs something rarer should ship it in its own <style>.
 *
 * Patterns are regex literals, so the colour families (gray red yellow green
 * blue indigo purple pink) and the spacing scale are spelled out in each
 * pattern that uses them; change every copy together.
 *
 * Rebuild with `python3 scripts/build_css.py` after changing this file.
