Sunsama

Build me a solo daily planner like Sunsama. Requirements: - A local web app on localhost:4400: Node + Express + better-sqlite3, server-rendered with a little vanilla JS for drag and drop. No frontend framework. - Today view, two columns: my Google Calendar events (read-only via googleapis, OAuth creds in .env) as a timeline, and today's task list beside it. - Tasks have title, estimate in minutes, project tag, done flag. Quick-add box at the top, plus a backlog panel of unplanned tasks I can drag into today. - Header shows planned minutes vs a daily budget from config (default 6h) and turns red when I overplan. - A /shutdown page for the end of day: walks each unfinished task, one keystroke to roll to tomorrow, send to backlog, or drop, then shows planned vs actual. - Keep per-day history in SQLite so a /week page can show the last 7 days of planned vs done. - Calendar is read-only: never write events. Out of scope: task-tool integrations (Todoist, Trello, email), mobile apps, and two-way calendar sync. - No accounts, no telemetry, everything local except the Google API calls. - README: Google Cloud console steps for the OAuth client · budget an hour, that console is the worst part of this build.
