Interop 2027: Temporal API proposal

Focus area proposal asking browsers to align on the Temporal API in the Interop 2027 cycle.

Problem

Dates and time zones in JavaScript still depend on the legacy Date object and extra libraries. Browsers need to agree on a shared, tested implementation of Temporal.

What I did

Submitted an Interop 2027 focus area proposal for the Temporal API to web-platform-tests/interop (issue #1381).
Asked developers to support the proposal and describe their own use cases on the issue.

Result

The proposal is open for the Interop 2027 selection.

Decisions

Argue from real developer use cases, because focus areas are chosen by evidence of developer pain.
