Treat it like a marketing artifact: one big idea, one CTA.\n\n## Workflow\n\n1. **Read the active DESIGN.md** (injected above). Email leans on the display\n font more than any other surface — pick the loudest type token in the DS\n for the headline lockup.\n2. **Pick the brand + product** from the brief. Generate a real wordmark, a\n real product name, and one real benefit sentence — no placeholders.\n3. **Layout**, in order, all centered inside a 600–680px column on a tinted\n page background (so the email body looks like an email, not the page):\n - **Masthead** — wordmark on the left + 3 short nav links (SHOP, JOURNAL,\n MEMBERS) on the right. Thin underline.\n - **Hero block** — a 16:9 product image placeholder. Use a DS-tinted\n gradient or a stylized SVG silhouette of the product (shoe, bottle,\n headphones, whatever the brief implies). Add a tiny brand stamp on the\n top-left and a colorway tag on the bottom-left.\n - **Eyebrow** — small caps, accent color, separated by `·` characters\n (e.g. \"NEW · MAX-CUSHION TRAINER · EMBER FLARE\").\n - **Headline lockup** — 2–3 line headline using the display font, all caps,\n extra-tight tracking. Apply a slight skew (`transform: skew(-6deg)`) on\n one accent word to give it a sporty parallelogram feel.\n - **Body** — 2–3 sentence paragraph, left-aligned, body font.\n - **Primary CTA** — solid pill or block button. One only.\n - **Specs grid** — 2×2 grid of (big number + unit + label) callouts using\n the display font for the numbers.\n - **Footer** — wordmark, address line, unsubscribe + view-in-browser links.\n4. **Write** a single HTML document:\n - `` through ``, CSS inline.\n - Center the column with `margin: 0 auto`. Set `body { background: }`\n so the email-on-page metaphor reads.\n - No external images — use inline SVG or DS-tinted gradient blocks for the\n product photo.\n - `data-od-id` on the masthead, hero, headline, CTA, specs.\n5. **Self-check**:\n - Email reads top to bottom in 8–10 seconds.\n - One CTA. Accent appears at most twice (eyebrow + CTA, or headline word).\n - Looks legible on a 480px window (column reflows, type drops one step).\n\n## Output contract\n\nEmit between `` tags:\n\n```\n\n\n...\n\n```\n\nOne sentence before the artifact, nothing after.\n","tagline":"A brand product-launch email — masthead with wordmark, hero image block,\nheadline lockup with skewed-italic accent, body copy, primary CTA, and a\nspecifications grid.
