+Nightly Report Router.
+
+Manual triggers for the night-vs-baseline sound report — the same entry point
+the scheduled morning tick will reuse.  Two endpoints:
+
+  GET  …/reports/nightly/view  → render and return the HTML inline (preview).
+                                 No write, no email.  Browser-friendly.
+  POST …/reports/nightly/run   → full run: build → write report.html/json to
+                                 disk → (dry-run) email.  Returns JSON result.
+
+Dates are the *evening* date of the night being reported (the 7/7 in "night of
+7/7 → morning 7/8").  Defaults to last night.  Baseline is optional; pass the
+baseline-week range to populate the comparison.
