v4.5.0

What's Changed

• Fix float-point precision, add unit options and DTCG-compliant values by @hefler in #26

Closes #21, #23, #24, #25.

Numbers

• Decimals no longer export with floating-point noise — 732.8 exports as 732.8, not 732.7999877929688. Every format.

Units

• New dropdown for numeric variables: none, px or rem, with a root font-size field when rem is chosen. CSS, Tailwind and JSON; JS and CSV keep exporting plain numbers.
• Import asks for the root font size when a file carries rem values, instead of silently rescaling them.

DTCG

• JSON now writes dimensions as {"value": 16, "unit": "px"} and colours as the Color Module object, per the 2025.10 spec. One option, on by default, restores the old "16px" and "#ff00ff" strings.
• $type no longer claims what a value cannot satisfy — an out-of-range fontWeight reports number. Values are never altered. JSON only; the CSV column and JS field are unchanged.
• Import reads colours in all fourteen colour spaces, converting the wide-gamut ones to sRGB with a warning, and picks a variable's type from its value so a fontWeight of "bold" imports correctly.

CSS

• The single-dash group separator is now available for plain CSS, not just Tailwind, so text/h1--line-height can export as --text-h1--line-height.

Interface

• The export preview and the scrollbars are legible in light theme.
• Long help tooltips became readable footnotes, options are reordered, and the CSS format is named "CSS & Tailwind".
