Browser Extension / Platform

PDX Matchday

Manifest V3 Chrome extension for the next Portland Timbers match: ESPN schedule with local cache and fallback, hourly background refresh, and a Firebase anonymous confidence poll. Independent fan project. A popup redesign is in active design — home/away color from the next fixture, Timbers and Thorns, standings, and settings — with Chrome still the first client of a larger platform (live match states, notifications, public web, iOS later).
