# Spendly Design System

## Overview

The interface is light, built on **Snow (#F7F7F8)** with **Deep Indigo (#17172B)** text, and **Light Purple (#FF6FD8)** as the main accent.

Type is set in **Inter** and **Arial**. Headlines run large; body text is 16px. Depth comes from soft drop shadows. Controls are pill-shaped.

Measured from [spendly.swiftaxon.com](https://spendly.swiftaxon.com/) on October 24, 2026 at 1440×900 and 390×844 from 69 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 14 roles, plus gradient stops #5B4CE0, #8A5CE7, #C664EA, #FF6FD8.

- **Snow (#F7F7F8):** Page background. Token `background`.
- **Deep Indigo (#17172B):** Primary text and headings, seen 3 times. Token `on-surface`, CSS `--ink`.
- **Near Black (#000000):** Headings and emphasis, seen 2 times. Token `on-surface-strong`.
- **Charcoal (#1A1A1A):** Secondary text, seen 4 times. Token `on-surface-variant`.
- **Cool Graphite (#3C3C43):** Muted text and metadata, seen 8 times. Token `on-surface-muted`, CSS `--cream`.
- **Cool Snow (#F5F4FB):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`, CSS `--paper`.
- **White 90% (#FFFFFFE6):** Cards and panels, seen 1 time. Token `surface-container`.
- **White (#FFFFFF):** Hover and pressed fills, seen 3 times. Token `surface-container-high`, CSS `--ink-navy`.
- **Near Black 4% (#0000000A):** Translucent fill for cards and controls, seen 3 times. Token `overlay`, CSS `--ink-navy-2`.
- **Near Black 6% (#0000000F):** Borders and dividers, seen 4 times. Token `outline`, CSS `--glass-border`.
- **Near Black 10% (#0000001A):** Secondary dividers, seen 3 times. Token `outline-variant`.
- **Light Purple (#FF6FD8):** Brand accent (CSS variable), seen 1 time. Token `primary`, CSS `--accent-2`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Indigo (#6C5CE7):** Brand accent (CSS variable), seen 12 times. Token `secondary`.

## Typography

**Inter** and **Arial** share the interface. Fallback stack: `Inter, sans-serif`.

- **body-md:** Inter 16px at weight 400. Body text.
- **body-sm:** Inter 12.5px at weight 400. Secondary and small text.
- **label-md:** Arial 14.5px at weight 500. Buttons, navigation and labels.
- **label-sm:** Inter 13px at weight 600. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 46% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3px, sm 8px, md 12px, lg 24px, xl 38px.
- **Gaps:** 12px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1120px.
- **Breakpoints:** 640px, 760px, 900px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(124, 108, 255, 0.3) 0px 6px 18px 0px`
- `rgba(0, 0, 0, 0.5) 0px 30px 80px 0px`

Hairline rings and inset highlights also appear: `rgba(124, 108, 255, 0.3) 0px 0px 0px 3px`.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **md (13px):** 32 elements.
- **full (9999px):** 16 elements.
- **lg (20px):** 12 elements.
- **sm (10px):** 4 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-outline (“Forgot your password?”):** #FFFFFF fill, #17172B text, 13px/600, 999px radius, padding 8px 16px, border 1px solid #0000000F.
- **button-secondary (“Log in”):** transparent fill, #FFFFFF text, 15.5px/600, 999px radius, padding 13px 24px, shadow `rgba(124, 108, 255, 0.3) 0px 6px 18px 0px`.
- **button-ghost (“Overview”):** transparent fill, #3C3C43 text, 14.5px/500, 13px radius, padding 11px 14px.
- **input-field (“Username”):** #0000000A fill, #000000 text, 15px/400, 20px radius, padding 11px 12px, border 1px solid #0000001A, shadow `rgba(124, 108, 255, 0.3) 0px 0px 0px 3px`.
- **card:** #FFFFFFE6 fill, #1A1A1A text, 16px/400, 20px radius, padding 32px 28px, border 1px solid #0000000F, shadow `rgba(0, 0, 0, 0.5) 0px 30px 80px 0px`.

## Do's and Don'ts

- Do use #F7F7F8 for the page and lift surfaces in small steps: #F5F4FB, #FFFFFFE6, #FFFFFF.
- Do keep text in 4 levels: #17172B, #000000, #1A1A1A, #3C3C43.
- Do use #FF6FD8 as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (8px, 12px, 24px).
- Do make buttons and chips fully rounded (9999px); most other elements use 13px corners.
- Don't introduce new font families beyond Inter and Arial.
- Don't use #FF6FD8 for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.18s, 0.15s, 0.1s, 0.4s.

- **Easing:** `ease`, `cubic-bezier(0.2, 0.8, 0.2, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
