A reading log that wants to be a ledger.

Marginalia is a personal reading tracker dressed as a printed library ledger — warm paper, hairline rules, italic display type, a single oxblood accent. It began as a design handoff: a high-fidelity prototype I rebuilt from the ground up in this site’s stack.

Track what you’re reading, log a session, save a passage as marginalia, rate a finished book, and watch the 26-week heatmap fill in. It’s a live demo — everything is interactive, but the ledger lives only in memory: a refresh wipes your changes and restores the sample data.
