Self-contained examples for the PiP overlay API (POST /api/pip), each with a CSP-safe query-param overlay (external JS), config.example.json, zero runtime deps, an offline test, and a README: - PIP-Announce-Broadcast manual one-shot message to a screen/group - PIP-Weather-Widget Open-Meteo current conditions (keyless) - PIP-Air-Quality Open-Meteo US AQI widget (keyless) - PIP-Crypto-Ticker CoinGecko price strip (keyless) - PIP-News-Ticker scrolling RSS/Atom headlines - PIP-Room-Status-Calendar ICS-driven Available/Busy room sign - PIP-Event-Countdown client-side countdown, auto-clears at zero - PIP-Welcome-Board rotating welcome/birthday cards from CSV - PIP-Fundraiser-Thermometer goal-progress bar from local/URL JSON - PIP-QR-Rotator rotating QR codes, encoded client-side - PIP-Incident-Webhook event-driven: red on firing, clear on resolved Also includes the CAP-AU (NSW RFS) and US NWS/NOAA emergency-alert monitors that push expiry-aware PiP overlays.
