/**
 * consent.css - Nano Commerce cookie-consent banner + preferences.
 *
 * THEME-AGNOSTIC by design: this ships with the platform and runs on every
 * store regardless of its theme, so it does NOT depend on store.css. It is a
 * self-contained, solid (not translucent) surface that stays legible over any
 * background, and it adapts to the visitor's light/dark preference on its own.
 *
 * FULLY SKINNABLE: a designer building a store for their customer can re-brand
 * the whole widget from CSS alone, no markup changes, by overriding these public
 * knobs on :root (or on .nc-consent-root). Each has a "-dark" variant so light
 * and dark can be branded independently; anything left unset keeps the default.
 *
 *   --nc-accent          accent for the primary button + the switch    (#ff4d00)
 *   --nc-accent-ink      text colour ON the accent                     (#ffffff)
 *   --nc-bg        / --nc-bg-dark        panel background        (#ffffff / #17171b)
 *   --nc-fg        / --nc-fg-dark        main text               (#1b1b1f / #f2f2f4)
 *   --nc-muted     / --nc-muted-dark     secondary text          (#55555d / #a6a6b0)
 *   --nc-border    / --nc-border-dark    hairline borders        (light/dark rgba)
 *   --nc-shadow    / --nc-shadow-dark    panel shadow
 *   --nc-radius          corner radius                                    (16px)
 *   --nc-font            font family                             (system stack)
 *
 * Everything else is private (--_x) and derived. No inline scripts or styles are
 * required, so it lives happily inside a strict Content-Security-Policy.
