## What it is
A Sass library that generates modular scales—proportionally related value lists—for sizing type and layout elements in web design. It provides an ms(n) function and configurable base/ratio settings to compute harmonious sizes directly in stylesheets.

## Use cases
- generate a typographic scale in sass
- size headings using the golden ratio
- create harmonious spacing values in scss
- build a multi-stranded type scale with multiple bases
- replace hardcoded font sizes with proportional scale steps
- align responsive breakpoints to a modular scale

## When to choose
- you use Sass/SCSS and want mathematically harmonious type and spacing sizes
- you want a lightweight, dependency-free design-token generator for typography
- you need multi-stranded scales with multiple base values

## When to avoid
- your project does not use Sass or a Sass-compatible build pipeline
- you prefer modern CSS custom properties or a PostCSS-based solution
- you need a full design-token or theming framework rather than a scale calculator
