// Parses WIAA 2A/3A/4A state finals (places 1-8) from pdftext.js output. Handles three layouts:
//  A (2026): place line, "#bib" line, name, year, school, mark
//  B (2025): fixed-width lines "  1 #  669 Name  12 School  10.71  -1.4"
//  C (2022-2024): School, Yr, Name, place, mark tokens on separate lines
// Usage: node parse-multi.js <txt> <year>  -> JSON rows on stdout
