Class KeyboardController

Keyboard shortcuts for chart navigation. Attached to a focusable HTMLElement (the top canvas with tabindex=0). Active only when the element has focus, so page-level shortcuts are not captured.

Key	Action
← / →	Pan by 5 candles
Shift + ← / →	Pan by 25 candles
↑ / ↓	Zoom in / out
+ / =	Zoom in
- / _	Zoom out
Home	Jump to the oldest candle
End	Go to live edge (re-enable follow)
0	Fit visible (reset candleWidth)
F	Fit all (show entire buffer)
