/**
 * Shared Tailwind theme preset — SINGLE SOURCE OF TRUTH for the editor's
 * Tailwind color/theme config. The root, React, and Vue Tailwind configs all
 * extend this preset so the palette can never drift between adapters.
 *
 * Every color here maps to a CSS variable defined in
 * packages/core/src/styles/editor.css. The shadcn tokens use the
 * `hsl(var(--x) / <alpha-value>)` form so opacity modifiers (e.g. bg-primary/90)
 * work; the --doc-* chrome tokens are plain var() (used mostly in raw CSS).
 *
 * CommonJS so the ESM adapter configs can `require()` it (Tailwind loads configs
 * via jiti, which supports require). Each adapter config still owns its own
 * `content` globs and `important: '.ep-root'` scoping.
