# CatchyChat Design System

- **Page margin:** 32px on each side of full-width sections.
- **Breakpoints:** 600px, 640px, 767px, 768px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`

Hairline rings and inset highlights also appear: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgb(255, 255, 255) 0px 0px 0px 0px, rgb(24, 29, 37) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px`.

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **sm (8px):** 40 elements.
- **xs (6px):** 24 elements.
- **md (12px):** 24 elements.
- **lg (16px):** 8 elements.
- **xl (24px):** 4 elements.

## Components

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

- **button-primary (“Sign Up”):** #FF7033 fill, #FFFFFF text, 12px/700, 8px radius, padding 0px 12px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`.
- **button-secondary (“Start Chatting Now”):** transparent fill, #FFFFFF text, 14px/700, 8px radius, padding 8px 16px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px`.

- **link:** transparent fill, #45556C text, padding 0px.

## Do's and Don'ts

- Do use #E7EAEF for the page and lift surfaces in small steps: #EDEFF2, #F1F5F9, #FFFFFF.
- Do keep text in 4 levels: #181D25, #0F172B, #45556C, #67717E.
- Do reserve #FF7033 for primary actions and key highlights.
- Do set headlines in Bricolage Grotesque with tight tracking (-0.015em).
- Do reuse the measured spacing steps (8px, 16px, 32px).
- Do use 8px corners on most elements; larger surfaces also use 6px, 12px and 16px.
- Don't use #67717E for body text; it reaches 4.11:1 on #E7EAEF. Keep it for large text or metadata.
- Don't introduce new font families beyond Bricolage Grotesque, Inter and JetBrains Mono.
- Don't use #FF7033 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.15s, 0.2s, 0.3s. Longer ambient animations run 3s, 1s, 1.6s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `linear`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
