 /**
- * Statutory figures for the years this book covers, on the new tax regime.
+ * Statutory figures per financial year, keyed '2026-27'.
+ *
+ * Nothing is compiled in. The values live in m_tds_fy_config, are edited on
+ * Organization › TDS Configuration, and are loaded into this registry by
+ * `TdsConfigService` before any TDS screen opens (see `tdsConfigResolver`). A
+ * year with no entry makes the computation throw rather than guess.
 *
 * For a customer who has opted out onto the old regime, `basicExemption` and
 * `nilTaxCeiling` are lower and vary by age; pass an override through
 * `TdsContext.config`.
- *
- * Thresholds and rates did not change at the 2026 changeover — ₹50,000,
- * ₹1,00,000 for senior citizens, 10%, and 20% without PAN carried straight
- * across. What changed is the declaration and the return it is reported in.
