Bug: load-more link used items.length as next offset, causing offset=20
to lead to page 20 again instead of page 40.
Fix: Use offset + items.length for correct next page calculation.
With 20 items per page: offset=0→20→40→...
Verification:
- Astro build: 0 errors
- Filter preservation: params preserved in URL
- Last page: items.length < totalItems check works
- Invalid offset: Number.isInteger check on line 16
Remove existing offset parameter before adding new one to prevent
duplicate query parameters like ?offset=20&offset=40.
Fix: Use URLSearchParams.delete() to remove old offset before setting
new value, ensuring only one offset parameter in the URL.
Verified: Astro build succeeds with 0 errors
- Add selected={hours === '6/12/72'} to all period options (was only on 24)
- Ensures correct UI state when URL has hours=6/12/72
- CSS for filter-compact-hidden already correct (display:none!important)
- Filter fallback details working for no-JS mobile
- Pagination (R09) already handles offset preservation
