Updates baseline data using the latest versions of @webref/css and web-features.
This PR is autogenerated by the "Update Baseline" GitHub Action.
Summary by CodeRabbit
New Features
Added baseline coverage for interest-delay, timeline-related, display-state, resizable, interest-button, and additional alignment CSS properties and values.
Added flex-related property values and the repeat value for column-rule-color.
Updates
Updated baseline availability information for several animation, timeline, alignment, and animation-duration features, reflecting their 2026 baseline status.
The web-features development dependency range advances to ^3.45.0. The baseline data adds CSS properties, values, selectors, and media conditions, and updates baseline levels for animation, scroll, and view timeline features.
The web-features development dependency range changes to ^3.45.0. The baseline map adds interest-delay properties, media conditions, and the interest-button selector, including normal values for interest-delay properties.
Expand alignment and flex values src/data/baseline-data.js
The alignment maps gain values, flex gains content, justify-content gains values, place-content gains a value map, and column-rule-color gains repeat.
eslint/css#599: This earlier baseline-data update advances the web-features range to ^3.44.0 and adds some flex-related values also present in this update.
Suggested reviewers:nzakas, dmartens
Merge Risk: Minimal · up to ecff8
The baseline update is mergeable after normal checks. The alignment-safety and animation-shorthand reporting gaps are pre-existing and can be addressed separately.

Explanation
The title "fix: update baseline data" matches the main change. The PR refreshes src/data/baseline-data.js with new baseline entries and status updates, and bumps the web-features dev dependency from ^3.44.0 to ^3.45.0. The title is short and specific, but it uses the generic word "update" and a conventional-commit prefix of "fix" for what is largely a data refresh. It does not name the affected features, which is acceptable because the title need not cover every detail.

- Around line 1273-1275: Update the place-items shorthand availability data so
generated values include the availability of safety modifiers and their
align-items component. Ensure safe center is not treated as available in 2021
and reflects the 2024 availability of align-items.
- Line 1550: Update the animation-duration entry so auto uses the longhand’s
actual availability, causing a 2023 baseline check to warn; preserve auto
availability for the animation shorthand and other properties.

Check shorthand duration availability
For a 2023 baseline, the rule accepts animation: auto but warns on animation-duration: auto. Check the shorthand duration against the longhand availability while preserving other uses of auto.
