One-Click Fibonacci Retracement Indicator

I need a TradingView Pine Script indicator that lets me drop a full Fibonacci retracement suite onto any intraday chart with just one click. The core idea is speed: as soon as I select a swing high or low, all the standard retracement levels should populate automatically and stay anchored, updating only when I choose a new reference point.

Intraday performance is essential, so the script must be light, respond instantly, and respect Trading View's real-time data limits. Visual clarity matters too—color-coded bands, optional percentage labels, and the ability to toggle individual levels on or off without digging through settings will make the tool genuinely usable during fast-moving sessions.

Deliverables:
• Clean, well-commented Pine Script v5 code
• Settings panel for level colors, opacity, and labels
• Step-by-step install/use note so I can load and test it immediately on any intraday symbol

I’ll confirm completion once I can reproduce the one-click placement, see all retracement a 1 second chart using Renko bars.
