Brand Tagline Generator Webpage

Design and implement an original focused creative utility responsive webpage for Signal Tagline Studio, aimed at small AI product teams. Information architecture: A focused brief form, audience and tone controls, grouped tagline directions, a shortlist tray, rationale notes and a compact originality checklist. Interactions: Generate clearly labeled draft directions, compare selected lines, edit inline, copy a shortlist and reset every input without losing focus. Responsive behavior: Stack the brief above results on mobile, preserve readable controls and keep the shortlist accessible without covering content. Use semantic HTML, accessible labels, visible keyboard focus, sensible heading order, readable contrast, and reduced-motion support. The primary call to action is “Start free”. Required constraints: Do not fabricate trademarks, endorsements or performance claims; mark every output as a draft for human review. Use realistic product copy instead of lorem ipsum. Do not add fake customer logos, invented usage metrics, fabricated testimonials, or inactive controls. Keep the page fast and avoid dependencies that are unnecessary for the requested interaction.
