/*
 * OurClassMate brand lockup — shared across landing, auth and registration.
 *
 * Two variants of one mark:
 *   image  → the full PNG lockup. Its wordmark is navy, so light surfaces only.
 *   text   → circular mark + typeset wordmark. Recolourable, so it survives dark surfaces.
 *
 * Size with --lockup-h (image) or --lockup-mark (text) on the element itself.
