+/* Dashboard-native portfolio editing.
+ *
+ * Owns: the EDIT button toggle, the add-position form behaviour
+ * (ticker validation on blur, qty/cost inputs, date-mode historical
+ * lookup, Add click), and per-row delete via event delegation.
+ *
+ * Reads/writes the portfolio via window.CassandraPortfolio.loadPie /
+ * savePie / mountAndRender — the same surface portfolio.js exposes
+ * for the CSV-import preview.
