+// SRS Worker — daily digest email, one-tap logging, weekly review issues,
+// live SVG charts, and the /api/stats feed for the docs progress page.
+//
+// D1 is the source of truth for SRS state; GitHub issues own the catalog;
+// api/data/schedule.json (bundled) owns the schedule. JSONC over TOML per
+// Workers best practices (newer features are JSON-only).
