You are an AI design tool. Follow the design rules file below exactly. Make one self contained HTML file: a one-pager, 816px wide by 1056px tall, for Newton Research, aimed at agencies. Content to use: the line 'Meet Newton, your team of marketing analytics agents'; the three approved stats; a button 'Start free trial' (Newton offers a free 30 day trial). Reply with only the HTML, starting with <!doctype html>. No commentary.

# Newton Research design rules (demo, v1)

Rules for AI design tools. Built by Eric Jefferson from Newton's public site
(newton.ai live CSS, read 2026-10-22). Not an official Newton file.

## 1. Brand principles
- Airy and calm. Lots of off white space, one idea per block.
- Dark purple ink on light tints. Purple is the accent, never the background of a whole page.
- Plain, confident words. Lead with what the agents do for the reader.

## 2. Color
| Token | Hex | Use |
|---|---|---|
| ink | #2b2544 | All body text, headlines, button fill |
| ink-hover | #05030c | Button hover only |
| accent | #8c6eff | Links, one highlight word, small marks |
| accent-strong | #745bd5 | Hover and highlight states |
| tint-purple | #f9f8fc | Page background |
| tint-blue | #f9fbfe | Alternate section background |
| line | #e9eef4 | Borders, dividers, card outlines |
| lavender | #e3ddf8 | Soft fills, chips |
| muted | #696677 | Secondary text, captions |
| mark-blue | #89abde | Logo mark ONLY. Never text, never fills. |

## 3. Typography
- Headlines and body: Open Sauce Sans. Weights 400, 500, 600, 700.
- Eyebrows: Space Mono, uppercase, 0.75rem, letter spacing 0.08em, color muted.
- Headline: 600 weight, tight line height (1.1). Body: 400, line height 1.55.
- Never use a third typeface.

## 4. Layout
- 12px radius on cards and images. 100px radius on pills and buttons.
- Generous padding: 48px minimum around a one-pager's content.
- Left aligned text. No centered paragraphs.

## 5. Components
- Button: pill, ink fill, white 14px text at 500 weight, capitalized.
- Stat block: big number in ink, 600 weight. Label under it in muted. A stat is never shown without its source line.
- Card: white fill, 1px line border, 12px radius.

## 6. Usage rules
- Only use claims printed on newton.ai. Copy numbers word for word with their qualifier.
- Approved stats: "x10 More output"; "126 hours saved" with "up to 126 hours every month";
  "300% more accurate" with "than leading LLMs out of the box on benchmark testing".
- No dashes as punctuation.
- Footer on every page: newton.ai
