Tokens

Rho's decoded design system: background #FFFFFF, text #000000, accent #05ECC1, link #CDFBF2, primary #05ECC1; type scale h1 88px / h2 88px / body 12px; 8px spacing base; 8px base radius. The single interactive/action color is #05ECC1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#05ECC1`
accent	`#05ECC1`
link	`#CDFBF2`
secondary	`#64748B`
button_bg	`#05ECC1`
button_text	`#151716`

Using these colors

Action color #05ECC1 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #05ECC1 — one role, not several (the action color).
accent #05ECC1 — 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 #CDFBF2 — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #64748B — 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.

# Rho — Design System

> light, professional, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#05ECC1` |
| accent | `#05ECC1` |
| link | `#CDFBF2` |
| secondary | `#64748B` |
| button_bg | `#05ECC1` |
| button_text | `#151716` |

**Using these colors**

- **Action color** `#05ECC1` — 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 `#05ECC1` — one role, not several (your action color).
- **accent** `#05ECC1` — 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** `#CDFBF2` — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#64748B` — 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): `#FFFFFF` 80.5% · `#0C101F` 11.6% · `#9CA6A5` 4.1% · `#262930` 2.2%

## Typography

- Heading: **Basier** _(free fallback: Newsreader)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 88px / 400 · lh 88px · tracking 1.28px |
| h2 | 40px / 600 · lh 40px · tracking 0.8px |
| h3 | 24px / 400 · lh 22px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 14px · tracking 0.14px |

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

> **Fonts —** Basier may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 90px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 4px
- card: 32px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.84 0.1608 173.06)` / `oklch(0.2 0.0037 164.66)` | none | 4px | 0px 16px 0px 16px | 500 14px / 0.14px | none |
| secondary | `#FFFFFF` / `#0C101F` | 1px solid rgb(255, 255, 255) | 2px | 12px 10px 12px 10px | 600 13.008px / 0.13008px | none |

**States (measured, not guessed)**

- primary hover: background `oklch(0.9 0.1363 172.97)`
- primary focus: outline `1px dashed rgb(0, 0, 0)`
- transition: `all 0.22s cubic-bezier(0.88, 0.19, 0.58, 0.78)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.08) 0px 4px 16px 0px`

## Motion
- durations: 220ms (dominant) · 600ms · 200ms
- easings: `cubic-bezier(0.88, 0.19, 0.58, 0.78)` (dominant) · `ease`
- animated properties: background-color, opacity

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

## 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.
