chart

Render financial charts via the local chart web app (workspace at the repo root — Hono server + React front end, port 5199). Four chart types: intraday capital-flow line (flow) and cross-symbol signed-bar comparison (cohort) — both Recharts — plus SEPA strategy dashboard (sepa) and short-term multi-timeframe prediction dashboard (intraday) — both TradingView Lightweight Charts. Multi-timeframe K-line review lives inside intraday (the standalone kline chart type was removed). The server fetches Longbridge data itself (kline / capital flow) and computes all indicators (MA, MACD, RS, trend template, volume profile, divergence/beichi detection) in TypeScript; the caller only POSTs {type, symbol, ...} to /api/charts and gets back {id, url, technicals?}. Charts persist as data JSON under journal/charts/data/. url now points at where the chart actually lives: sepa/intraday land on the symbol page (http://localhost:5199/symbol/<SYM>?analysis=<id>), flow/cohort land on the home page for that date (http://localhost:5199/?date=YYYY-MM-DD); old http://localhost:5199/charts/<id> links still work and redirect there.
