Why this prompt works
This prompt works because it names the business, the kind of shop, and the feeling it wants. "Specialty coffee shop" tells Blockora the audience cares about craft, and "premium" points at restrained type and generous spacing rather than bright promo blocks.
It also stays specific without over-explaining. One sentence covers the business, the format, and the tone, which is enough for the menu, story, and visit sections to come out in the right order.
