Partiful — Design System

light · modern · medium · custom · confidence 90% · deep decode

Partiful throws type like confetti: TWK Lausanne at a massive 112px/825 ('Parties are back') over event-photo chaos, with 24px body and deliberately plain 4px-radius black buttons as the sober chaperone. Sticker graphics, emoji bursts and RSVP cards supply the mess — an events app whose design system is the after-photos, held together by one very heavy grotesque.

# Partiful — Design System

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

Partiful throws type like confetti: TWK Lausanne at a massive 112px/825 ('Parties are back') over event-photo chaos, with 24px body and deliberately plain 4px-radius black buttons as the sober chaperone. Sticker graphics, emoji bursts and RSVP cards supply the mess — an events app whose design system is the after-photos, held together by one very heavy grotesque.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0000EE` |
| accent | `#000000` |
| link | `#9CD7FF` |
| button_bg | `#000000` |
| button_text | `#0000EE` |

**Using these colors**

- **Action color** `#000000` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#000000` — one role, not several (your action color).
- **accent** `#000000` — 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.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #000000, not this.
- **link** `#9CD7FF` — fails contrast on the background (~1.5:1) — 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): `#3E4AAC` 15.1% · `#140B16` 14% · `#D29397` 13.6% · `#964E91` 11.9%

## Typography

- Heading: **TWK Lausanne Pan 850** _(free fallback: Newsreader)_
- Body: **TWK Lausanne** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 112px / 825 · lh 90px · tracking -3.36px |
| h2 | 48px / 500 · lh 48px · tracking -0.96px |
| h3 | 42px / 400 · lh 50px |
| body | 24px / 550 · lh 34px · tracking -0.48px |
| small | 22px / 400 · lh 31px · tracking -0.88px |

- Weight ladder: 400 · 500 · 550 · 700 · 825 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 30px, 40px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 4px
- card: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#0000EE` | none | 4px | 0px 24px 0px 24px | 400 12px | none |
| secondary | `#FFFFFF` / `#0000EE` | none | 4px | 0px 24px 0px 24px | 400 12px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(255, 255, 255, 0.8)`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `rgba(255, 255, 255, 0.796)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.1) 0px 0px 6px 0px`
- overlay: `rgba(0, 0, 0, 0.1) 0px 0px 20px 0px`

## Layout (measured)
- common grid: 2-col
- nav: 128px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 2124 | 288 | 2 | — | 0/0 | — |

## Motion choreography (measured)
- scroll reveal: 7 elements rest at opacity 0, translateY(100px) (7 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 809px · 1199px
- mobile (390px): hero 28px · body 12px · nav: inline

## 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.
