Levels renders metabolic health at poster scale: TT Hoves at 102px/500 ('See how food affects your health.') in white over macro food photography, 14-16px working text, zero-radius text CTAs in clinical teal #1D7D6C. Glucose curves and app screens supply the science while the oversized grotesque supplies the conviction — biometrics presented like a health manifesto.

Tokens

Levels's decoded design system: background #FFFFFF, text #131413, accent #9FC5BC, link #9FC5BC, primary #1D7D6C; type scale h1 102px / h2 56px / body 16px; 4px spacing base; 0px base radius. The single interactive/action color is #131413 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F0F0`
border	`#DBDBDB`
text	`#131413`
text_muted	`#6C6D6C`
primary	`#1D7D6C`
accent	`#9FC5BC`
link	`#9FC5BC`
secondary	`#2650CB`
button_bg	`#131413`
button_text	`#FFFFFF`

Using these colors

Action color #131413 — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #9FC5BC — one role, not several (the action color).
accent #9FC5BC — accent for emphasis — keep it rare on the page.
primary #1D7D6C — a brand color — but the call-to-action uses #131413, not this.
secondary #2650CB — 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.

# Levels — Design System

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

Levels renders metabolic health at poster scale: TT Hoves at 102px/500 ('See how food affects your health.') in white over macro food photography, 14-16px working text, zero-radius text CTAs in clinical teal #1D7D6C. Glucose curves and app screens supply the science while the oversized grotesque supplies the conviction — biometrics presented like a health manifesto.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DBDBDB` |
| text | `#131413` |
| text_muted | `#6C6D6C` |
| primary | `#1D7D6C` |
| accent | `#9FC5BC` |
| link | `#9FC5BC` |
| secondary | `#2650CB` |
| button_bg | `#131413` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#131413` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#9FC5BC` — one role, not several.
- **accent** `#9FC5BC` — accent for emphasis — keep it rare on the page.
- **primary** `#1D7D6C` — a brand color — but the call-to-action uses #131413, not this.
- **secondary** `#2650CB` — 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): `#231F1C` 66.6% · `#0F0D0E` 21% · `#484743` 6.7% · `#C8D6B9` 5.7%

## Typography

- Heading: **TT Hoves** _(free fallback: Newsreader)_
- Body: **TT Hoves** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 102px / 500 · lh 97px · tracking -5.12px |
| h2 | 56px / 500 · lh 58px · tracking -2.24px |
| h3 | 45px / 500 · lh 47px · tracking -1.79px |
| body | 14px / 400 · lh 20px |
| small | 13px / 600 · lh 16px · tracking 0.13px |
| eyebrow | 14px / 600 · tracking 2.24px |

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

> **Fonts —** TT Hoves may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 6px, 8px, 10px, 12px, 14px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 128px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 8px
- card: 10px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(16, 21, 30, 0.9)` / `#82E9CB` | 1px solid rgba(130, 233, 203, 0.2) | 10px | 12px 10px 12px 10px | 600 13.008px / 0.13008px | none |
| secondary | `#FFFFFF` / `#131413` | none | 8px | 8px 16px 8px 16px | 600 14px | none |

**States (measured, not guessed)**

- primary focus: outline `1px solid rgb(222, 222, 222)`
- secondary hover: background `oklab(0.999994 0.0000455678 0.0000200868 / 0.9)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 150ms (dominant)
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, background-color, border-color, outline-color

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.
