# Imperium Brand Kit (canonical)

The one official Imperium brand system. Everything a human, an AI model, or a website codebase needs
to produce on-brand Imperium material. Self-contained: fonts are pre-installed, no CDN, no external
fetch. Precedence within the kit: BRAND-BOOK.md wins over everything, then tokens.json /
imperium-tokens.css, then AGENTS.md, then the process docs in downloads/skills. If any file
OUTSIDE the kit contradicts it, the kit wins.

## Start here
1. **`BRAND-BOOK.md`** - who Imperium is, voice, visual system, entity, do/don't. Read this first.
2. **`imperium-tokens.css`** - the design tokens. `@import` or `<link>` it, then use the CSS custom
   properties. Never hardcode hex.
3. **`tokens.json`** - the same tokens, machine-readable, for feeding into a codebase or AI tool.
4. **`imperium-master-sheet.html`** - the rendered master sheet (also served at brand.imperiumos.ai). The ONLY visual sheet.
5. **`ai-image-prompt-pack.md`** - prompts for generating on-brand images (Higgsfield / GPT Image 2).
6. **`fonts/`** - Emilio family + Switzer, woff2, pre-installed.

## The system in one line
Emilio Light headline, Switzer body, one green (Racing Green `#11462C`), at most one Ember `#E23A28`
accent, 40px corners (locked 2026-07-27), paper on green, ink on paper. Greens only. No warm browns. No mono.

## Locked decisions (Alex 2026-07-26)
- **Primary green `#11462C`** (the v4 `#004225` proposal was NOT adopted).
- **Ember accent `#E23A28`** bright.
- **Greens only** - champagne / taupe / walnut removed entirely.
- **Emilio + Switzer** - JetBrains Mono, Cinzel, and the Zodiak / Hanken / Plex proposal all removed.
- **Two separate brands:** Imperium (this kit) and the Alex Kaymakanov personal brand (Fraunces +
  champagne) stay distinct by design. See BRAND-BOOK.md section 10.

## Colour (steps 100 / 300 / 400 / 600 / 700 / 800 / 900)
| Token | Key hex | Role |
|---|---|---|
| Racing Green | `#11462C` (700) | PRIMARY |
| Mint | `#4CB782` (300) · `#D8EBDD` (100) | vivid supporting green |
| Bali | `#3FA085` (400) | jade accent green (never blue) |
| Deep Green | `#0A1F14` | darkest brand green |
| Ink | `#15130E` | the black |
| Bone | `#F4F1EA` | the "white" |
| Paper | `#F7F6F1` | working surface |
| Paper Sage | `#EDF2E8` | default page ground |
| Console Ground | `#0C1712` | dark dashboard ladder |
| Ember | `#E23A28` · bright `#FF4632` | the ONE accent, sparingly |

## Governance
- This kit is canonical. Per-project DESIGN.md files inherit and may only tighten, never contradict.
- Version history: [CHANGELOG.md](CHANGELOG.md) — updated on every meaningful deploy.
- Requests / corrections → alex@imperium-growth.com.
- The `.claude/skills/imperium-brand.md` skill points every future asset task at this kit.
- Superseded files (`brand-colors.md`, `style-system/master-style-blueprint.md`,
  `palette-v2-proposal-2026-07-26.md`, `higgsfield-brand-prompt-pack.md`) and the interim
  `imperium-styleguide.html` were DELETED 2026-07-29 so no competing guidance exists; git history keeps them.
