Built for Newton

Four concept pieces in your brand.

One for each kind of request in your post: a case study with an email, a sales deck, an event kit and a design system for AI tools. Each one stays inside your brand and stretches it into a new format.

Concept 1 · Case study

Dentsu case study, with an email header.

A leave-behind a seller can send after a first call, and the email that carries it. The page tells the dentsu story at a glance. The email gets the reader to it.

Answers: case studies · email templates

Built from

Your partnership release with dentsu and your homepage. Every name, quote and number is from them.

Stays in the brand

Your lavender tint, ink purple type, robot mark and pill buttons. Nothing new added to the system.

Reusable

One case study layout and one email header. Swap the customer, the headline and the three tiles.

Answers: sales decks · pitch presentations

Built from

Your Unlimited Analytics launch release: the feature names, the MMM line and the budget shift scenario, word for word.

Stays in the brand

Ink purple and white slides, the robot mark and your pill style. A light slide for the speed line, dark slides for the rest.

Concept 3 · Event

Event kit: backdrop, banner, tote and sticker.

An 8 by 8 foot booth backdrop, a retractable banner, a tote and a sticker. All of it built on two of your own lines.

Answers: trade show branding · swag

Built from

“Put AI agents to work on your behalf” and “We think math is cool.” The stats are the ones on your homepage.

Stays in the brand

Ink purple, lavender tint and the robot mark scaled up. At booth size, less is easier to read.

Reusable

Swap the headline per show. The banner, tote and sticker reuse the same two lines.

Concept 4 · AI design system

Design rules an AI can follow.

The design system written as a markdown rules file, a page an AI tool made from it, the one mistake it made, and the rerun with the fix.

Answers: design system in markdown · AI design tools

Built from

Your post asks for “structured markdown files covering brand principles, color, typography, layout, imagery, components, and usage rules”. The colors and type are from newton.ai public CSS.

Stays in the brand

Every token is one your site already uses. The usage rules only allow the stats printed on newton.ai, with their qualifiers.

Reusable

When a review finds a gap, add a rule. Rule 7 below is the example. The same file can go to any AI tool that reads markdown.

Step 1 · The rules file

Mistake: the AI drew its own logo. Rules v1 had no logo rule.

The same page. Rules v1 had no logo rule, so the AI drew a four point star filled #89abde next to the words. Newton's real mark is a robot face.

Step 4 · Run again with rules v2

The one-pager the AI made from rules v2, with the real Newton logo
Same brief, rules v2 and the logo file. The AI placed the real Newton logo. Review still reads every line: it added one sentence of its own.

Rule 7 · DESIGN-v2.md

7. Logo (added in v2 after review)

  • Use only the supplied Newton logo SVG (wordmark #463e6b, robot mark #89abde).
  • Never draw, redraw or replace the logo or the mark. If no logo file is supplied, leave the space empty and say so.

Claude Code (Sonnet) made both pages from the rules file and a short brief: run 1 on 2026-10-23, run 2 on 2026-10-24. Each page is saved as it came out.
