Summary

Collection items sorted by a date field were not ordering chronologically. Dates within the same year appeared in arbitrary order because parseFloat("2025-04-01") returns 2025, making all dates in the same year compare as equal.

Changes

• Replace parseFloat() with Number() for numeric detection in all three collection sorting paths:
  • lib/page-fetcher.ts — SSR collection rendering
  • app/ycode/api/collections/[id]/items/route.ts — items API endpoint
  • app/ycode/api/collections/[id]/items/filter/route.ts — filterable collection endpoint
• Number("2025-04-01") correctly returns NaN, so date strings fall through to localeCompare where ISO format sorts chronologically
• Add empty-string guard to prevent Number("") (which is 0) from triggering false numeric comparison

Test plan

• Sort a collection by a date field in ascending order — verify chronological order
• Sort a collection by a date field in descending order — verify reverse chronological order
• Sort by a numeric field — verify numeric sorting still works
• Sort by a text field — verify alphabetical sorting still works
• Verify sorting works in the published website (SSR path)
• Verify sorting works in the editor canvas (API path)
• Verify sorting works with filterable collections (filter API path)
