/*! me-syntax 1.0.0 · colours for .me code · MIT · neurons.me
 *
 * One mapping layer: every token colour is a --me-syn-* variable, resolved in this order
 *   1. a .GUI theme syntax token, if the theme defines one   (--mui-palette-syntax-<name> / --gui-syntax-<name>)
 *   2. derived from the active .GUI theme's existing tokens   (--mui-palette-primary-main, ...), mixed toward the
 *      theme's text colour so small code text keeps its contrast in light and dark
 *   3. a plain fallback for pages without .GUI                (light / dark by prefers-color-scheme)
 * With me-syntax.js, MeSyntax.watchTheme() measures the active theme and writes --me-syn-* on <html>: per role it picks
 * the first theme hue that reaches 4.5:1 on the theme background and paper with the least mixing toward the text
 * colour and stays distinct from neighbouring roles (e.g. operator vs false). The ratios below are the static
 * fallback: the most saturated fixed mix that still passes 4.5:1 in all 8 .GUI themes, light and dark.
