Compositor is a typographic system for the web. Using vertical metrics, compositor trims the line-gap above and below text elements, realigns the glyphs to the baseline and implements space and size constraints that adhere to a baseline-grid rhythm.

• Font Size: Any font-size is allowed. The text's bounding box is rounded to the nearest grid row, above the cap-height.
• Leading: In compositor, leading specifies the space between lines of text, unlike baseline-to-baseline in traditional typography.
• Measure: The line-width in `ch` units.

The compositor algorithm is also available as an experimental implementation in tailwind-compositor. ReactJS version coming soon in raster-ui.
