   VELA REAL ESTATE — concept demo for Swiss Web Bureau
   World: the concierge key board of a grand lakeside hotel. Oxblood lacquer,
   brass, bone enamel. Every property is a key on a hook; taking the key IS
   requesting a private viewing, and the hook's state is the property's state.
   Self-contained: local fonts, no CDN, no framework, no third-party script.
