*Summary*
CSS text-decoration-inset controls how far underlines, overlines, and
line-through decorations are inset from or extended beyond text run
edges. It supports auto, length, and percentage values, including
one-value and two-value syntax for setting the start and end offsets.
This lets developers adjust decoration spacing and create reveal
effects with native text decorations instead of background gradients
or additional elements.

*Web Feature ID*
text-decoration <https://webstatus.dev/features/text-decoration>
*Motivation*
This change implements CSS text-decoration-inset (CSS Text Decoration
Level 4), including percentage values. It gives authors direct control
over decoration inset and reduces the need for wrapper/pseudo-element
workarounds used to fine-tune underline/overline/line-through rendering.

Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github
issues in the project for the feature specification) whose resolution
may introduce web compat/interop risk (e.g., changing to naming or
structure of the API in a non-backward-compatible way).
