Increase — Design System

light · professional · medium · tailwind · confidence 92% · deep decode

Increase sets 'Enterprise-grade banking APIs' in Klim's Untitled Sans at 90px/700 — a deliberately unstyled typeface at maximum size, the typographic equivalent of a well-drafted contract. Slate #1A2B3B buttons at 8px radius, ledger-precise layout, and no decorative color: banking infrastructure that dresses like the regulator is watching, because it is.

Tokens

Increase's decoded design system: background #FFFFFF, text #1A2B3B, accent #1A2B3B, link #1A2B3B, primary #687887; type scale h1 16px / h2 16px / body 16px; 4px spacing base; 0px base radius. The single interactive/action color is #1A2B3B — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Increase — Design System

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

Increase sets 'Enterprise-grade banking APIs' in Klim's Untitled Sans at 90px/700 — a deliberately unstyled typeface at maximum size, the typographic equivalent of a well-drafted contract. Slate #1A2B3B buttons at 8px radius, ledger-precise layout, and no decorative color: banking infrastructure that dresses like the regulator is watching, because it is.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F2F3` |
| border | `#DCDFE1` |
| text | `#1A2B3B` |
| text_muted | `#717B85` |
| primary | `#687887` |
| accent | `#1A2B3B` |
| link | `#1A2B3B` |
| secondary | `#1F2937` |
| button_bg | `#1A2B3B` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1A2B3B` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent` `#1A2B3B`, `link` `#1A2B3B`, `secondary` `#1F2937`, `button_bg` `#1A2B3B` are visually the same color (Δ11) — treat as one role (your action color).
- **accent** `#1A2B3B` — 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** `#687887` — a brand color — but the call-to-action uses #1A2B3B, not this.
- **Page coverage** (full-page screenshot pixels): `#EBEEF0` 29.4% · `#34C1FB` 18% · `#FEFEFE` 13.9% · `#1A2B3B` 13.6%

## Typography

- Heading: **Untitled Sans** _(free fallback: Newsreader)_
- Body: **Untitled Sans** _(free fallback: Newsreader)_
- Mono: **Input Mono-4c4a0ba0f7fa02b9** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 90px / 700 · lh 90px · tracking -5.4px |
| h2 | 40px / 700 · lh 44px · tracking -1.6px |
| h3 | 32px / 700 · lh 36px · tracking -1.28px |
| body | 14px / 500 · lh 20px |
| small | 13px / 400 · lh 20px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 30px, 32px — snap all gaps/padding to these

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

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#1A2B3B` | 1px solid rgb(237, 240, 242) | 8px | 10px 15px 10px 15px | 500 14px | none |
| secondary | `#1A2B3B` / `#FFFFFF` | none | 8px | 5px 10px 5px 10px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#F5F6F7`
- secondary hover: background `#132030`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 500ms · 180ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.25, 0.46, 0.45, 0.94)`
- 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.

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

## Layout (measured)
- nav: 65px fixed · border-bottom 1px solid rgba(0, 0, 0, 0.05)

## Motion choreography (measured)
Load order: `div.animate-slideFadeOverlay` @0ms → `div.absolute`×8 @795ms → `div.absolute`×6 @961ms
- scroll reveal: 3 elements rest at opacity 0, animate in over 1s cubic-bezier(0.23, 1, 0.32, 1) (3 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 450px · 640px · 768px · 960px · 1160px · 1280px
- mobile (390px): body 16px · 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.
