+Caterium v17.6.1 — Chat photo compression + server memory counters
+Date: 2026-09-07
+
+1. Photos selected in chat are optimized in the browser before upload.
+   - Maximum side: 2048 px.
+   - Target size: about 2 MB.
+   - Absolute attachment limit remains 15 MB.
+   - Non-image files are unchanged; GIF/SVG are not recompressed.
+   - Browsers without DataTransfer fall back to the original chat upload path.
+
+2. Developer Console now receives server-side memory metrics:
+   - PostgreSQL database size.
+   - Supabase Storage size.
+   - Storage object count.
+   - Total server footprint (database + Storage).
+   - Per-bucket Storage breakdown is also returned by the RPC.
+
+3. Supabase migration: SUPABASE-V17.6.1-CHAT-STORAGE-GUARD.sql.
+
+4. GitHub QA initialization race fixed:
+   - Playwright waits for SunSafe and SunPdfEngine before invoking them.
+   - Added an automated large-photo compression test.
+
+5. PWA cache bumped to v66 / v17.6.1-chat-storage-guard.
+
+Release flow: feature/chat-storage-guard-v1761 -> GitHub QA + Cloudflare preview -> main -> Cloudflare production.
