Built the PostHeader.astro component per the design spec. It accepts props {title, date, type, readingTime}, formats dates with toLocaleDateString, renders a centered header with content type badge, h1 title, and meta line with date/reading time. Has responsive typography stepping down at 719px and 479px breakpoints. All 39 tests pass and npm run build succeeds.
