Radar de Demanda por Eventos

Use my Veetal Connect data to build an "Event Demand Radar" for Barcelona,
covering the next 12 months.

I want to know which events will drive hotel demand in the city, how hard they'll
push it, and when to price for them. Work out what data you need and fetch it.

Build it as a single self-contained web page I can open and share:

- A year view: one bar per month showing how much hotel demand that month carries.
  I click a month to explore it.
- The selected month: its events ranked by how hard they squeeze the city, each
  showing how busy it gets and how many roomnights it brings.
- An event detail: how demand builds and fades day by day, which hotel tiers absorb
  it, when the booking window opens and closes, who actually shows up - separating
  the people who sleep in a hotel from locals who don't - and how far out from the
  venue they stay.
- Surface where attendance is misleading: big crowds that generate little hotel
  demand, and smaller events that generate a lot.
- Flag anything that pushes the city past its room capacity.

Two layouts, switchable: a full page, and a compact floating widget pinned to the
bottom-right corner that shows the month navigator and that month's top events.

Clean and modern, works in light and dark. Use only real values from my data -
never invent numbers. If something isn't available, leave it out.
