/* brand.css — per-instance STRUCTURAL brand overrides.
 *
 * Empty by default. The kernel ships this file so the <link> in Layout always
 * resolves; an instance overrides it through the brand overlay
 * (instances/<name>/brand/brand.css) to go beyond palette tokens — e.g. tweak the
 * chrome via its stable hooks (.nova-appbar, .nova-journey-header,
 * .nova-journey-footer), swap a logo's size, or add a banner.
 *
 * For colours/radius, override nova-tokens.css instead (the whole UI reads those
 * via var() at runtime — no rebuild). Use this file only for structure the tokens
 * can't express. All chrome is built on semantic tokens, so most rebrands need
 * only nova-tokens.css and never touch this file.
