Decoded design system

Notion Calendar's decoded design system: background #FFFFFF, text #0D0D0D, accent #191918, link #A39E98, primary #FFF5E0; type scale h1 96px / h2 72px / body 16px; 4px spacing base; 6px base radius. The single interactive/action color is #0075DE — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0075DE — the single interactive color; only on things you click or must notice, never large fills.
• secondary, button_bg are all #0075DE — one role, not several (the action color).
• accent #191918 — accent for emphasis — keep it rare on the page.
• primary #FFF5E0 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #0075DE).
• link #A39E98 — fails contrast on the background (~2.7:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

# Notion Calendar — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0D0D0D` |
| text_muted | `#686868` |
| primary | `#FFF5E0` |
| accent | `#191918` |
| link | `#A39E98` |
| secondary | `#0075DE` |
| button_bg | `#0075DE` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0075DE` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `secondary`, `button_bg` are all `#0075DE` — one role, not several (your action color).
- **accent** `#191918` — accent for emphasis — keep it rare on the page.
- **primary** `#FFF5E0` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #0075DE).
- **link** `#A39E98` — fails contrast on the background (~2.7:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 88.7% · `#AAB3BB` 3.1% · `#0E0D0D` 3% · `#ECDBBC` 2.8%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 600 · lh 100px · tracking -4.6px |
| h2 | 72px / 500 · lh 87px · tracking -2px |
| h3 | 54px / 700 · lh 56px · tracking -1.88px |
| body | 16px / 700 · lh 24px |
| small | 14px / 500 · lh 20px |

- Weight ladder: 400 · 500 · 550 · 650 · 700 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 4px, 5px, 6px, 8px, 10px, 12px, 14px, 15px, 16px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 8px
- card: 8px
- pill: 9999px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0075DE` / `#FFFFFF` | 1px solid rgba(255, 255, 255, 0) | 8px | 4px 14px 4px 14px | 500 16px | none |
| secondary | `#E6F3FE` / `#005BAB` | 1px solid rgba(255, 255, 255, 0) | 8px | 6px 15px 6px 15px | 500 16px | none |

**States (measured, not guessed)**

- primary hover: background `#005BAB`
- primary focus: background `#005BAB` · outline `2px solid rgb(0, 117, 222)`
- secondary hover: background `#F2F9FF`

## Shadows (elevation)
- overlay: `rgba(66, 35, 3, 0.03) 0px 8px 12px 0px, rgba(66, 35, 3, 0.03) 0px 2px 6px 0px`

## Motion
- durations: 200ms (dominant) · 150ms · 600ms
- easings: `cubic-bezier(0.42, 0, 1, 1)` (dominant) · `ease-in-out`
- animated properties: background-color, color, text-decoration-color, -webkit-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.

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

## Responsive (measured)
- breakpoints: 400px · 440px · 600px · 712px · 840px · 1080px
- mobile (390px): hero 42px · 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.
