Walkthrough

JSX type declarations in packages/runtime-dom/src/jsx.ts were updated: added enterkeyhint, deprecated enterKeyHint alias, added exportparts and part to HTML attributes, added fetchpriority to image attributes, removed enterkeyhint/enterKeyHint from InputHTMLAttributes, and added set: SVGAttributes to intrinsic SVG mappings.

Changes

Cohort / File(s)	Change Summary
JSX typings packages/runtime-dom/src/jsx.ts	- Added `enterkeyhint?: 'enter'

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

Potential attention points:

• Ensure deprecated enterKeyHint alias usage is correctly handled across the codebase.
• Verify fetchpriority union matches platform spec and other typings.
• Confirm adding set to SVG intrinsic mappings does not shadow or conflict with existing SVG elements or attributes.

Poem

I nibble on tokens and types at night,
Hopping through attributes until they're right.
Parts and hints and priorities appear,
An SVG set bounds safely near.
A joyful rabbit celebrates with a bite 🐇
