# Convergent Systems

> `convergent-systems@1.0.0`

Convergent Systems builds civilization-grade software at the intersection of artificial intelligence, human resilience, developer productivity, and systems architecture. The brand expresses institutional restraint and mathematical precision: a hexagonal mark with six radial axes converging on a centered point, set against deep-space blue-blacks with cyan, gold, and ember accents.
Tagline: "Civilization-Grade Software for a Converging World." Founding principle: "Careful software is built for outcomes, not engagement."

### Palette

**Convergent Deep Space** · `convergent-deep-space@1.0.0` · MIT

> Dark-first palette extracted from the Convergent Systems brand site (convergent-systems.co). Deep-space blue-blacks for the canvas, cool off-white for text, and three vibrant accents — cyan, gold, orange — each with a softer hover variant. The gold accent is the brand's signature, used in the hexagonal-spiral mark. Designed for dark mode; light-mode role mappings provide a sensible inversion (cream canvas, deep-space text) while preserving the same three accent hues so the brand identity survives a mode switch.

## Rules

### 🛑 error (12)

#### `enumMembership` → `typography.heading.fontWeight`

- **allowed:** 700, 800

> Headings on convergent-systems.co use weight 800 (`clamp` font-size with letter-spacing -0.03em). Lighter weights compromise the institutional voice; weights above 800 are unavailable in the Inter variable font's static cuts on the brand's CDN. 

#### `numericRange` → `typography.wordmark.letterSpacing`

- **min:** `0.18`
- **max:** `0.18`
- **unit:** `em`

> The wordmark uses 0.18em letter-spacing as captured on the brand site. Deviating breaks the calibrated visual rhythm. 

#### `numericRange` → `typography.section-label.letterSpacing`

- **min:** `0.32`
- **max:** `0.32`
- **unit:** `em`

> Section labels use 0.32em letter-spacing, uppercase, weight 700. The wider tracking signals categorical organization, not body text. 

#### `forbiddenTreatment` → `logo.mark`

- **treatments:** stretched, rotated, recolored, drop-shadow, on-busy-photo, inverted-without-variant

> The mark is mathematical. Stretching breaks the hexagonal proportions; recoloring breaks the gold-signature identity. Use the appropriate light/dark wordmark variant rather than filtering the source. 

#### `variantSelection` → `logo`

- **use:** `wordmark-dark`
- **when:** `backgroundColorScheme="dark"`

> Use the dark-theme wordmark on deep-space-dark backgrounds.

#### `variantSelection` → `logo`

- **use:** `wordmark-light`
- **when:** `backgroundColorScheme="light"`

> Use the light-theme wordmark on parchment / light backgrounds.

#### `colorChoice` → `logo.mark.fill`

- **allowed:** solar-gold
- **forbidden:** solar-gold-soft, frost-cyan, ember-orange, any-non-gold

> The mark color IS the brand identity. Gold #F4C75E and only that. Soft variants are for hover/background; the mark itself is the anchor color. 

#### `contrastRatio` → `text-primary`

- **against:** `background`
- **minRatio:** `4.5`
- **standard:** `WCAG-AA`

> Snow-0 on Deep-Space-0 gives ~16:1; well above AA. Required for body text legibility on the dark canvas. Verify when introducing new role-color pairings. 

#### `contrastRatio` → `roles.colors.primary`

- **against:** `background`
- **minRatio:** `3`
- **standard:** `WCAG-AA-large`

> Frost-Cyan on Deep-Space-0 must remain perceptible at link size. Below 3:1 (AA-large), interactive affordance is lost. 

#### `contextRestriction` → `roles.colors.warmth`

- **forbiddenContexts:** error-state, validation-failure, destructive-action

> Ember-orange is a warmth/ambient accent (radial glows, secondary CTA). It is NOT the error color. Using it for failure states conflicts with its established positive-warm meaning. 

#### `accessibilityRequirement` → `*`

- **standard:** `WCAG-AA`
- **criterion:** `1.4.3`

> WCAG 2.1 Success Criterion 1.4.3 (Contrast Minimum) — Level AA. The brand's institutional voice demands accessibility as table stakes, not aspiration. 

#### `fontPairing` → `typography.heading`

- **requires:** `body`
- **minSizeRatio:** `1.8`

> The site's hero uses clamp(2.2rem, 4.2vw, 3.6rem) for headings against 1.15rem body — a ratio of roughly 2-3×. The 1.8× floor keeps headlines unmistakable even at the smaller clamp. 

### 💡 recommendation (2)

#### `numericRatio` → `typography.body.lineHeight`

- **min:** `1.6`
- **max:** `1.7`

> Body text on convergent-systems.co uses line-height 1.6–1.65. This range preserves readability at the established 1.15rem size. 

#### `compositionConstraint` → `roles.colors.frost-cyan`

- **pairsWith:** roles.colors.solar-gold
- **doesNotPairWith:** roles.colors.ember-orange

> The brand pairs cyan + gold as the dominant duo (cool + warm across the spectrum). Cyan + orange together fights for attention without resolving into hierarchy.
