/* Company Brain design tokens and shared primitives.
 *
 * Extracted from docs/ui/prototype.html, which is the design spec for the
 * workspace. Every page links this file, so a colour or a type step is defined
 * once here and nowhere else -- no page carries its own token block.
 *
 * The base layer (page background, type scale, default weight) is scoped to
 * `body.brand` rather than `body`. Only pages that have been moved onto the new
 * design opt in; the ones still on the old glass styling link this file for the
 * tokens and are left visually untouched until their own restyle lands. Adding
 * the class is what flips a page over.
