+//! `lapaloma-financial` — OHLC y candlesticks.
+//!
+//! Buffer: 6 floats por bar `[t, o, h, l, c, v]`. Agregación
+//! preserva volatilidad (max(h)/min(l), no LTTB — ver sección 3.2):
+//! time-bucketing con fallback a index-bucketing cuando todos los
+//! timestamps colapsan.
+//!
+//! Re-usa `lapaloma-cartesian` para viewport, ejes y gestures;
+//! sólo aporta el `CandlestickSeries` y la lógica de aggregación.
