Score Card Generator
Print-ready score cards for an indoor boulder competition, straight from the participant export.

Feed it the participant export and a mapping of which boulders each category climbs, and it prints the score cards. Interface and cards in Dutch, French and English, set independently — a Dutch organiser can print French cards for francophone participants.
It replaced a Word template, a mail merge, and someone writing boulder numbers on sixty cards by hand the night before.
Three constraints shaped it, and all three pushed the same way — toward one HTML file with no build step:
- It has to run offline. A sports hall has bad wifi at the worst possible moment. You open the file from a USB stick and it works.
- Nothing may leave the device. Participant lists are names of minors. All parsing and rendering is client-side; at runtime there is no network call to make, because there is nothing to call.
- Printing is the browser’s job. Ctrl+P, save as PDF, done. No PDF library.

- Frans oefenen — French vocabulary practice in both directions, on a Leitner schedule, with the French word read aloud.
- Maaltafels — Times tables 1–12, scheduled on recall speed rather than on right-or-wrong alone.
