Brand Guidelines Skill

This skill ensures all design work adheres to the project's established design system defined in styles/main.css.

Design Tokens Reference

Spacing Scale

Use these spacing tokens for consistent layouts:

• --xxs: 0.125rem (2px)
• --xs: 0.25rem (4px)
• --s: 0.5rem (8px)
• --m: 1rem (16px) — base unit
• --l: 1.25rem (20px)
• --xl: 1.5rem (24px)
• --xxl: 2rem (32px)
• --xxxl: 3rem (48px)

Usage: Prefer CSS custom properties over hardcoded values.

Copypadding: var(--m);
margin-block-end: var(--xxl);
gap: var(--s);

Color Palette

Neutrals (Light Mode)

• --white-1: hsl(200, 8%, 88%) — primary white
• --white-2: hsl(0, 0%, 88%) — secondary white
• --black-1: hsl(360 0% 0%) — pure black
• --black-2: hsl(46 94% 119%) — accent black
• --black-3: hsl(200 0% 16%) — primary dark
• --black-4: hsl(0 0% 20%) — secondary dark
• --black-5: hsl(0 0% 47%) — mid gray

Grays

• --gray-1: hsl(200, 8%, 45%) — primary gray
• --gray-2: #6d7f88 — secondary gray

Blues (Primary Brand)

• --blue-1: hsl(200 100% 32.9%) — dark blue
• --blue-2: hsl(201 44% 43%) — brand blue (links)
• --blue-3: hsl(204 100% 51%) — bright blue
• --blue-4: hsl(203 89.2% 52.9%) — accent blue

Oranges (Accent)

• --orange-1: hsla(30 60.7% 58% / 0.66) — text shadow
• --orange-2: hsl(38.8 100% 50%) — bright orange
• --orange-3: hsl(13.9 95.2% 67.1%) — coral
• --orange-4: #777 — muted orange

Semantic Colors

• --color-brand: hsl(200 11% 48%) — brand color
• --text-color: hsl(200 8% 16%) — body text
• --link-color: var(--blue-2) — link color
• --selection-color: var(--gray-1) — text selection
• --text-shadow: var(--orange-1) — text shadow

Important: Colors use OKLCH color space when supported via @supports (color: rgb(from white r g b)) for better perceptual uniformity.

Typography

Font Family

Copy--font-stack:
    "Recursive", system-ui, -apple-system, BlinkMacSystemFont, "Segoe UI",
    Roboto, Open-sans, "Droid Sans", "Helvetica Neue", Helvetica, Arial,
    sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";

Primary font: Recursive (variable font)

Font Sizes

• --f-base: 14px — minimum font size
• --font-base: clamp(var(--f-base), calc(var(--f-base) + 1.92vmin), 1.5rem) — responsive base

Recursive Variable Font Settings

Control the Recursive font's variable axes:

• --recursive-wght: 400 (default weight, range: 300-1000)
• --recursive-CASL: 0 (casual axis, 0 = linear, 1 = casual)
• --recursive-MONO: 0 (monospace axis, 0 = sans, 1 = mono)
• --recursive-slnt: 0 (slant, 0 = upright, -15 = italic)
• --recursive-CRSV: 0.5 (cursive, 0 = Roman, 1 = cursive)

Example usage:

Copyh1 {
    --recursive-wght: 700;
    --recursive-CASL: 0.64;
}

Other Tokens

Border Radius

• --border-radius: var(--s) (8px)

Animation

• --link-ease: cubic-bezier(0.2, 0.8, 0.2, 1)
• --link-timing: 444ms

Guidelines for Implementation

DO:

✓ Always use CSS custom properties from the design system ✓ Maintain spacing scale consistency (multiply base units) ✓ Use semantic color tokens (--text-color, --link-color) over raw colors ✓ Leverage OKLCH colors for modern browser support ✓ Use Recursive font variable axes for expressive typography ✓ Follow the established animation timing and easing

DON'T:

✗ Hardcode colors, spacing, or font values ✗ Create new spacing values outside the scale ✗ Use arbitrary color values not in the palette ✗ Override the font stack without justification ✗ Add new custom properties without updating this guide

Workflow

When implementing design changes:

1. Read styles/main.css:102-167 to verify current tokens
2. Reference this skill for correct token usage
3. Use existing tokens; propose new ones if necessary
4. Test in both light and dark modes (OKLCH support check)
5. Document any new tokens added to the system

Dark Mode

The design system includes dark mode support. Key overrides:

Copy@media (prefers-color-scheme: dark) {
    --text-color: var(--white-1);
    --text-shadow: var(--white-2);
    --bkgnd: var(--black-3);
}

Ensure any new color usage respects the existing dark mode pattern.

Questions?

If a design requires a token not in the system, consult with the team before adding it to maintain consistency.
