/**
 * SvGrid's built-in design-system theme presets (shadcn/ui, Tailwind, Material 3,
 * Excel, Fluent 2, ...). Each preset carries an explicit light + dark palette;
 * resolving one (plus a light/dark mode) yields the full `--sg-*` token set that
 * restyles the whole grid - not just the accent.
 *
 * Pure, framework-agnostic data + helpers - safe to import from Node or the
 * browser. `@svgrid/enterprise`'s Studio layer builds its `ProjectTheme`-aware
 * wrapper on top of this module instead of keeping its own copy.
