Workout Log Pr Tracker

A real gym log, not a glorified notes app. Computes estimated 1-rep max with the real Epley formula and flags a PR the instant you beat your all-time best — weighted lifts by e1RM, bodyweight moves by rep count. Exercise library, per-exercise progress charts (hand-drawn SVG), workout history, session volume, JSON export/import. Zero dependencies, fully offline. Playwright-verified: every demo session matches an independent re-simulation exactly. (AI-assisted build; verified working.)
