Superlist — Design System

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

Superlist stacks its promise in Haffer XH at 88px/600 — 'Tasks, notes, and plans. Finally in one app.' — white on deep ink #181824, with 16-18px body and flat zero-radius CTAs. Kinetic color blocks and app panels in the brand's red-coral cut through the dark; the Wunderlist lineage shows in how loudly it believes in lists.

# Superlist — Design System

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

Superlist stacks its promise in Haffer XH at 88px/600 — 'Tasks, notes, and plans. Finally in one app.' — white on deep ink #181824, with 16-18px body and flat zero-radius CTAs. Kinetic color blocks and app panels in the brand's red-coral cut through the dark; the Wunderlist lineage shows in how loudly it believes in lists.

## Colors

| Role | Value |
|------|-------|
| bg | `#181824` |
| surface | `#242430` |
| border | `#373742` |
| text | `#ECECEE` |
| text_muted | `#9B9BA1` |
| primary | `#0000EE` |
| accent | `#4F6BED` |
| link | `#4F6BED` |
| secondary | `#26253B` |
| button_bg | `#FFFFFF` |
| button_text | `#26253B` |

**Using these colors**

- **Action color** `#FFFFFF` — 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 `#4F6BED` — one role, not several.
- **accent** `#4F6BED` — accent for emphasis — keep it rare on the page.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **secondary** `#26253B` — 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): `#181826` 63.4% · `#322342` 13.9% · `#45314D` 10.1% · `#49699C` 6.8%

## Typography

- Heading: **Haffer XH SemiBold** _(free fallback: Newsreader)_
- Body: **Haffer XH** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 88px / 600 · lh 84px · tracking -1.76px |
| h2 | 70px / 400 · lh 84px · tracking -1.4px |
| h3 | 48px / 600 · lh 53px · tracking -0.96px |
| body | 18px / 400 · lh 22px · tracking -0.22px |

- section rhythm: 56px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 100px
- card: 20px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#0000EE` | none | 8px | 0px 0px 0px 0px | 400 12px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Shadows (elevation)

- card: `rgba(0, 0, 0, 0.08) 0px 10px 15px 0px`

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--ticker-offset` | `0px` |

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

## Layout (measured)
- container max 1500px
- nav: 100px relative · backdrop blur(29px)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 119 | 1324 | — | — | 56/0 | — |
| 1444 | 495 | — | — | 0/0 | — |

## Motion choreography (measured)
- `div.framer-1o3cg8s` — transform translateY(-50px)→translateY(-46.0594px) — 400ms (delay 200ms) · spring-like

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

## Responsive (measured)
- breakpoints: 809px · 1199px · 1399px
- mobile (390px): hero 48px · 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.
