Builds a self-contained, responsive HTML brochure from structured sections: the first section becomes the hero, [features] items form a numbered card grid, [cta] renders a call-to-action band, and headings, paragraphs, images, buttons, columns and footers reuse the email block language. Choose brand colour, light or dark theme, font, feature columns, title and tagline; the page includes a print stylesheet with page margins, no-break sections and visible link targets. A text outline is produced alongside. The preview uses placeholder images and inert links. Everything runs locally.
