+                              pbRatio, trailingPEG1Y, ...). Endpoint serves a flat JSON list of
+                              dated rows; we read the LATEST (max date) row.
+                                GET {base}/tiingo/fundamentals/{ticker}/daily?startDate=YYYY-MM-DD
+                                → [{date, marketCap, enterpriseVal, peRatio, pbRatio, trailingPEG1Y}]

+                              debtEquity, grossMargin, profitMargin, revenueQoQ, bookVal, epsDil, ...).
+                              Endpoint serves a JSON list of period entries; we take the LATEST
+                              (max date) entry and flatten its statementData sections (overview +
+                              incomeStatement + balanceSheet + cashFlow) into {dataCode: float(value)}.

+
+Both default a startDate window of ~800 days (well inside entitlement; gives several recent quarters
+of statements and a long daily-metrics history) and read the most-recent available period.
+
+Auth: header `Authorization: Token <key>` with TIINGO_API_KEY (env). The key is used ONLY in the
+request header — never logged or interpolated into a URL.
+
+NOTE: shapes above are coded to the documented/verified Tiingo response shapes; this build env had
+no TIINGO_API_KEY, so the first live run will confirm. None-valued fields are skipped.
