Sustainability Week Event Planner

I need a small, responsive web app that lets visitors explore the Sustainability Week Zurich programme and build their own personalised schedule. Please use nothing more than vanilla HTML, CSS and JavaScript—no React, no frameworks—so the final code stays lightweight and easy for our team to maintain.

Core screens
• Programme: displays all events, browsable by day, with filters for campus, category and event language.
• My Week: shows only the talks a visitor has saved; they can add or remove items and their choices must persist in the browser (localStorage is fine).

Key features
• Event cards open into a detail view that includes a cancellation label (if flagged), an embedded Google Map and an external registration link.
• English-only interface; no multilingual toggle needed.
• I will supply a PDF containing sample events—treat this as the initial data source while you wire everything up. Once the structure is proven, we will switch to the final dataset in the same format.

Deliverables
1. Clean, well-commented source code hosted in a public Git repo.
2. One-click setup notes (e.g., “open index.html” or simple npm script if you prefer a lightweight build step).
3. A short test report or screen recording showing it working on mobile and desktop breakpoints.
4. Live demo link by 3 November; polished final hand-off by 6 November 2026.
5. Licence-free assets only; all third-party code must be MIT or similarly permissive.

The project is a fixed price in the USD 100-150 range. When you reply, please share at least one example of a small JavaScript-only site or planner you have built, confirm your exact fee within that band, and tell me you can hit both milestones.
