Hearth: a booking page for a small ceramics studio

Design a single, responsive web page for Hearth Clay Studio, a neighbourhood pottery studio that runs evening wheel-throwing classes. The page has one job: help a first-time visitor pick a class and request a spot. Include, in this order: 1. A header with the studio name and a single "Book a class" action. 2. An introduction: one headline and one short paragraph about what a beginner can expect. 3. A class schedule with exactly these three classes: - Intro to the Wheel: Tue 6:30–8:30 pm, $48, 4 spots left - Glazing Basics: Thu 6:30–8:30 pm, $42, sold out - Weekend Open Studio: Sat 10 am–1 pm, $30, 9 spots left Make the price, the time and availability easy to compare. A sold-out class must look clearly unavailable. 4. A booking form: name, email, class (chosen from the three), and an optional note. The submit button reads "Request a spot". Show how a field error looks for an invalid email. 5. A footer with the address (14 Kiln Lane), opening hours and an Instagram link. Constraints: use real text only (no lorem ipsum). The page must work at 1440 px desktop and 390 px mobile widths. Text and controls must be readable and usable with a keyboard. Use no stock photography; if you want imagery, use simple shapes or illustration. Choose your own visual style, but keep it calm and crafted, not corporate.
