# lltg.co -- Design System Reference

## 1. Visual Theme & Atmosphere

Structured editorial portfolio with strong typographic hierarchy. The layout relies on proportion and rhythm rather than colour to establish visual order, resulting in a quietly authoritative presence.

The overall mode is **dark**, with a editorial, serif-driven typographic identity. Depth is entirely absent -- the composition is rigorously flat.

---

## 2. Color Palette & Roles

### Design Tokens

- `var(--hw-active-bg-color)`: `#F3F4F6`
- `var(--hw-border-color)`: `#D1D5DB`
- `var(--hw-component-bg-color)`: `#FFFFFF`
- `var(--hw-group-color)`: `#57595C`
- `var(--hw-group-bg-color)`: `#FFFFFF`
- `var(--hw-invalid-color)`: `#EF4444`
- `var(--hw-dialog-label-color)`: `#1D1D1D`
- `var(--hw-focus-color)`: `#2563EB`
- `var(--hw-option-bg-color)`: `#FFFFFF`
- `var(--ds-white-100)`: `#FFFFFF`
- `var(--ds-black-100)`: `#000000`
- `var(--ds-grey-100)`: `#F8F8F8`

### Computed Roles

- **background (body)**: `rgb(255, 255, 255)`
- **text (body)**: `rgb(32, 32, 32)`

**Key observations:** Token-driven colour system -- use CSS custom properties as the single source of truth. Never hardcode hex values. Dark-mode-first palette.

---

## 3. Typography Rules

**body** -- ft-primary, 14px, weight 400, line-height 14px

**Hierarchy principle:** A single typeface (ft-primary) handles all levels. Size and weight alone establish rhythm.

**What is absent:** No monospace or system-UI fallback. The serif identity is deliberate -- do not substitute.

---

## 4. Component Styling

**Border radii:** No border radii detected -- corners are sharp throughout.

**Interactive states:**
- `a[href]`: tag: a "@siddhartharun", default: [object Object], hover: null, focus: [object Object]
- `a[href]`: tag: a "Instagram", default: [object Object], hover: null, focus: [object Object]
- `a[href]`: tag: a "Kodak Portra 800", default: [object Object], hover: null, focus: [object Object]

**Buttons & controls:** Match the typographic register -- serif labels, generous line-height, understated borders.

---

## 5. Layout Principles

Spacing is minimal and relies on default browser margins.

No dominant padding pattern -- spacing is contextual.

Avoid introducing grid lines, dividers, or decorative rules unless absolutely necessary. Let whitespace do the structural work.

---

## 6. Depth & Elevation

No box shadows detected. Depth is achieved through colour contrast and spacing alone -- the design is intentionally flat.

Maintain the flat aesthetic throughout. If you must indicate overlapping layers (modals, tooltips), use border outlines or background tints rather than shadows.

---

## 7. Do's and Don'ts

**Do:**
- Respect the editorial, serif-driven typographic voice -- every element should speak the same typeface language.
- Use whitespace as a primary design tool. When in doubt, add space rather than elements.
- Reference CSS custom properties exclusively -- never bypass the token layer.
- Keep interactions subtle: micro-transitions at 150-200ms maximum.

**Don't:**
- Do not swap the serif for a sans-serif alternative. The editorial register depends on it.
- Do not add drop shadows, gradients, or decorative textures unless they are already present in the system.
- Do not use colour to communicate hierarchy -- spacing and scale do that work here.
- Avoid centring body text. The layout has a strong left-anchored reading rhythm.

## 8. Responsive Behavior

Breakpoints detected: 600, 768.

Honour the breakpoints extracted above.

On small screens, collapse multi-column layouts to a single column without compromising the typographic scale. The type should remain readable -- never below 14px rendered size.

---

## 9. Agent Prompt Guide

When generating UI components, extensions, or page sections for **lltg.co**, instruct the agent as follows:

> "Build in the style of lltg.co: structured editorial portfolio with strong typographic hierarchy. Use ft-primary as the primary typeface. Dark background, light text. No shadows or elevation. Token-driven colours via CSS custom properties. No animations -- immediate state changes only. Generous whitespace, strong typographic scale. Sharp corners throughout."
