# Brand Guide

## Sumi-e, not minimalism.

Traditional Japanese ink painting is three things: white paper, black sumi ink, and one red _hanko_ stamp pressed at the end. That is the whole system, and it suits a signature-led identity, because a signature is a brush stroke and a personal seal at once.

It sits _adjacent_ to wabi-sabi rather than inside it. The two agree on negative space, asymmetry, restraint and natural imperfection, and we follow both there. They part on colour: wabi-sabi is earth-derived and desaturated, and a saturated red would break it. Sumi-e permits exactly one, used sparingly.

The productive tension is that sumi-e wants emptiness while a firm deciding who to trust wants evidence. The resolution runs through every page: the opening is sparse and considered, and the sections behind it carry the proof. Restraint at the front, substance behind it.

## An experienced operator, not a salesperson.

**Marketing Engineer for law firms.** The label unifies marketing and engineering into one identity, but marketing judgment still leads; the engineering underneath is the reason to believe it, never a headline about tech. Audience decides the order: to a law firm, AI is _how_ the work happens and never the product. To an agency, the engineering is the product, because it is the thing they cannot hire.

### Direct

Say what you believe, without padding.

### Experienced

Authority from depth and clarity, not exaggeration.

### Analytical

Diagnose first. Recommend second.

### Hands-on

Not a presentation and a disappearance.

### Sceptical

Question vanity metrics, hype and agency theatre.

### Practical

The question is always: does this help the firm?

### Sounds like this

> If your SEO agency cannot explain what they did last month, you have a problem.

> AI isn’t a marketing strategy. It’s a tool. The strategy still has to make sense.

### Never this

> Your agency is stealing your money.

Direct is not hostile, and the brand is not anti-agency. Avoid corporate, motivational, hype-driven and buzzword-heavy registers — and avoid sounding machine-written: no em-dash cadence, no “it’s not just X, it’s Y”.

## Two grounds, one ramp, one seal.

The ground is never pure white, and the near-black is blue-black rather than neutral grey — real sumi ink has a cool cast, and the whole ramp inherits it. That single bias is why the neutrals read as chosen rather than inherited.

### Grounds

| Token          | Use                                               | Light   | Dark    |
| -------------- | ------------------------------------------------- | ------- | ------- |
| `--ca-paper`   | Page ground. Washi-toned, never pure white.       | #F6F5F2 | #111318 |
| `--ca-paper-2` | Raised surface: panels, form fields, quiet cards. | #EFEEEA | #17181D |
| `--ca-paper-3` | Banded section, for alternating rhythm.           | #EAE8E3 | #1E2026 |
| `--ca-rule`    | Hairlines and borders. The only separator we use. | #DFDDD7 | #2A2C33 |

### Ink ramp

| Token        | Use                                                  | Light   | Dark    | On ground         |
| ------------ | ---------------------------------------------------- | ------- | ------- | ----------------- |
| `--ca-ink`   | Headings and primary. Blue-black, not neutral grey.  | #111318 | #F1F0EC | 17.04:1 / 16.29:1 |
| `--ca-ink-2` | Body text, and any copy on a tinted surface.         | #3D3F47 | #C2C1BD | 9.63:1 / 10.31:1  |
| `--ca-ink-3` | Secondary text — on the base ground only.            | #63656B | #8C8D93 | 5.34:1 / 5.62:1   |
| `--ca-ink-4` | Decorative and disabled only. Never meaningful text. | #9A9CA3 | #5E606A | 2.52:1 / 2.97:1   |

### Seal

| Token             | Use                                                    | Light   | Dark    | On ground       |
| ----------------- | ------------------------------------------------------ | ------- | ------- | --------------- |
| `--ca-seal`       | Red TEXT and marks. Lifts on dark so it doesn't muddy. | #D0342C | #E8564A | 4.58:1 / 5.19:1 |
| `--ca-seal-solid` | Red FILLED surfaces. Pinned in both themes.            | #D0342C | #D0342C | 4.58:1 / 3.72:1 |

Ratios are computed at build time against each theme’s own ground. **--ca-ink-4** is decorative and disabled use only — the number above is exactly why it must never carry meaningful text. And **--ca-ink-3** is rated against the base ground; on a tinted band it falls below the threshold, so body copy there uses **--ca-ink-2**.

## Red is a seal, not a colour.

Red always has a job. Only one element in a view may compete to be it. If two things are fighting to be the red thing, one of them is wrong — and that single discipline is what keeps this reading as Japanese minimalism rather than a startup page with a red button.

### Permitted

- The seal mark and logo lozenge
- Primary CTAs and filled numbered marks, in `--ca-seal-solid`
- The brush underline, on one focal phrase per view
- Section eyebrows on dark grounds, and the eyebrow rule anywhere
- A single active state, and hairline accents

### Not permitted

- Headlines or body copy
- Large filled bands or page backgrounds
- Two elements competing to be the red in one view
- Small text on a tinted light ground
- A filled surface painted in `--ca-seal` rather than the solid

> Why the seal is two tokens
>
> White on the lifted dark-mode seal is only 3.58:1 and fails. White on `--ca-seal-solid` is 4.99:1 and passes. So every filled red surface is painted in the solid, in _both_ themes, and `--ca-seal` stays a text-and-mark colour.

## Three faces, one 1.333 scale.

**Fraunces** for display and headings, **Inter** for body and UI, **JetBrains Mono** for eyebrows and meta. Wide intervals suit sparse layouts. Running text caps at `62ch`, and headings balance.

| Token     | Use                 | Face  | Size     |
| --------- | ------------------- | ----- | -------- |
| `--ca-s8` | Display             | serif | 4.209rem |
| `--ca-s7` | Page title          | serif | 3.157rem |
| `--ca-s6` | Section heading     | serif | 2.369rem |
| `--ca-s5` | Sub-heading         | serif | 1.777rem |
| `--ca-s4` | Lede, pull-quote    | sans  | 1.333rem |
| `--ca-s3` | Body                | sans  | 1rem     |
| `--ca-s2` | Small, captions, UI | sans  | 0.875rem |
| `--ca-s1` | Eyebrow, meta, date | mono  | 0.75rem  |

## The rules that do the quiet work.

### Form

Near-square **2px radius** — nothing is rounded. Separation is always a **hairline rule**, never a shadow: there is no elevation anywhere in this system. Placement is asymmetric and off-grid; centring everything is the fastest way to make it look like a template.

### Motion

Slow, and never asking to be watched. Nothing bounces, pulses or loops. The house reveal is a soft fade with a slight rise, and reduced motion is always honoured.

- `--ca-dur-quick` 180ms
- `--ca-dur-base` 280ms
- `--ca-dur-slow` 620ms
- `--ca-dur-ink` 1500ms

### Imagery

Generated imagery is fine for texture, environment and project visuals. **Never for portraits** — on a site selling AI expertise, a detectably synthetic photo of the person is the one credibility hit that is hard to recover from. Portraits are real photography, graded to the palette.

Avoid: glowing circuitry, neural-network motifs, holographic UI, saturated gradients, lens flares, glossy chrome, high-key studio lighting, symmetrical centred compositions, or more than one accent colour.

## Do, and don’t.

| Do                                  | Don’t                              |
| ----------------------------------- | ---------------------------------- |
| One red element per view            | Two things competing to be the red |
| Seal-filled CTAs in --ca-seal-solid | Filled red using --ca-seal         |
| Washi ground                        | Pure #FFFFFF                       |
| Near-square radius, 2px             | Rounded cards                      |
| Asymmetric, off-grid placement      | Centring everything                |
| Hairline rules for separation       | Drop shadows and elevation         |
| Real photography for portraits      | Generated portraits                |
| Reuse the tokens and shared classes | One-off styles and new hex values  |

Source of truth: `brand/tokens.css` for values, `brand/BRAND.md` for the reasoning. This page is generated from the first of those. If something here disagrees with the site, the tokens win.
