Decoded design system

Obsidian's decoded design system: background #0F0F0F, text #EEEEEE, accent #7C3AED, link #BCBCBC, primary #7C3AED; type scale h1 60px / h2 36px / body 24px; 4px spacing base; 6px base radius. The single interactive/action color is #7C3AED — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #7C3AED — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #7C3AED — one role, not several (the action color).
• accent #7C3AED — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• link #BCBCBC — reads as a neutral UI color, not a link accent — verify against the reference (action = #7C3AED).
• secondary #8A5CF5 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Obsidian — Design System

> dark, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#0F0F0F` |
| surface | `#1C1C1C` |
| border | `#303030` |
| text | `#EEEEEE` |
| text_muted | `#999999` |
| primary | `#7C3AED` |
| accent | `#7C3AED` |
| link | `#BCBCBC` |
| secondary | `#8A5CF5` |
| button_bg | `#7C3AED` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#7C3AED` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#7C3AED` — one role, not several (your action color).
- **accent** `#7C3AED` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **link** `#BCBCBC` — reads as a neutral UI color, not a link accent — verify against the reference (action = #7C3AED).
- **secondary** `#8A5CF5` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#0F0F0F` 69.4% · `#1E1E1E` 25.5% · `#605673` 5.1%

## Typography

- Heading: **Inter**
- Body: **Roboto**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 600 · lh 60px · tracking -1.2px |
| h2 | 36px / 400 · lh 40px |
| body | 24px / 400 · lh 32px |
| small | 20px / 600 · lh 28px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 6px, 8px, 12px, 16px, 23px, 24px, 32px — snap all gaps/padding to these

## Radius
- base: 6px
- button: 8px
- card: 4px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#7C3AED` / `#FFFFFF` | none | 8px | 16px 24px 16px 24px | 500 20px | rgb(255, 255, 255) 0px 0px 0px 0px inset, rgba(255, 255, 255, 0.1) 0px 0px 0px 1px inset, rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px |
| secondary | `rgba(0, 0, 0, 0)` / `#BCBCBC` | none | 8px | 8px 12px 8px 12px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#8B5CF6`
- primary focus: outline `2px solid rgb(124, 58, 237)`
- secondary hover: background `#262626` · color `#FFFFFF`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px`
- card: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.25) 0px 25px 50px -12px`
- button: `rgb(255, 255, 255) 0px 0px 0px 0px inset, rgba(255, 255, 255, 0.1) 0px 0px 0px 1px inset, rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`

## Motion
- durations: 150ms (dominant) · 100ms · 250ms
- easings: `ease-in-out` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: color, background-color, border-color, text-decoration-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1120px
- nav: 90px fixed · border-bottom 1px solid rgba(0, 0, 0, 0)

## Motion choreography (measured)
- scroll reveal: 1 elements rest at translateY(86px), animate in over 0.1s cubic-bezier(0.4, 0, 0.2, 1) (1 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #A78BFA · no underline — hover #C4B5FD

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px
- mobile (390px): hero 51px · body 16px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
