// FLASH CRASH — the red-terminal panic. Cascades arm at bar boundaries
|
|
// (`cascade` chance per bar) and slam the walk downward for most of a bar
|
|
// with doubled volatility; the shader's panic wash (`p2`) floods the
|
|
// terminal red on every pulse while a cascade is running, and down-candles
|
|
// burn blood-red through the bloom. Pattern taught: the crash is CPU state
|
|
// (a beat-clocked cascade machine), the panic is shader state (uniform
|
|
// `cascade` + the p2 binding) — the two lock to the same bar.
