**ADIF Parser**: `src/backend/utils/adif-parser.js`
- `parseADIF(adifData)`: Parse ADIF format into QSO records
- Handles case-insensitive `<EOR>` delimiters (supports `<EOR>`, `<eor>`, `<Eor>`)
- Uses `matchAll()` for reliable field parsing
- Skips header records automatically
- `parseDCLResponse(response)`: Parse DCL's JSON response format `{ "adif": "..." }`
- `normalizeBand(band)`: Standardize band names (80m, 40m, etc.)
- `normalizeMode(mode)`: Standardize mode names (CW, FT8, SSB, etc.)

Both LoTW and DCL return data in ADIF (Amateur Data Interchange Format):
- Field format: `<FIELD_NAME:length>value`
- Record delimiter: `<EOR>` (end of record)
- Record delimiter: `<EOR>` (end of record, case-insensitive)
- Header ends with: `<EOH>` (end of header)

### Recent Commits
- `233888c`: fix: make ADIF parser case-insensitive for EOR delimiter
- **Critical bug**: LoTW uses lowercase `<eor>` tags, parser was splitting on uppercase `<EOR>`
- Caused 242K+ QSOs to be parsed as 1 giant record with fields overwriting each other
- Changed to case-insensitive regex: `new RegExp('<eor>', 'gi')`
- Replaced `regex.exec()` while loop with `matchAll()` for-of iteration
- Now correctly imports all QSOs from large LoTW reports
- `645f786`: fix: add missing timeOn field to LoTW duplicate detection
- LoTW sync was missing `timeOn` in duplicate detection query
- Multiple QSOs with same callsign/date/band/mode but different times were treated as duplicates
- Now matches DCL sync logic: `userId, callsign, qsoDate, timeOn, band, mode`
- `7f77c3a`: feat: add filter support for DOK awards
- DOK award type now supports filtering by band, mode, and other QSO fields
- Allows creating award variants like DLD 80m, DLD CW, DLD 80m CW
- Uses existing filter system with eq, ne, in, nin, contains operators
- Example awards created: dld-80m, dld-40m, dld-cw, dld-80m-cw
- `9e73704`: docs: update CLAUDE.md with DLD award variants documentation
- `7201446`: fix: return proper HTML for SPA routes instead of Bun error page
- When accessing client-side routes (like /qsos) via curl or non-JS clients,
the server attempted to open them as static files, causing Bun to throw
