Add product-specific session and token setup

 Edit `config.json` before running.
 
+Common URL, login credentials, login waits, and step delay stay at the top level.
+`setup.run_session` and `setup.run_token` are defaults for every enabled product.
+`setup.session` provides common session timing defaults.
+
+`products` contains separate `IDAS`, `RTM`, `UPC`, `RA`, and `REC` sections.
+Each product has its own `me_instance`, optional `session` timing overrides, and
+`token` settings (codes, delivery offset, expiry, and time sessions).
+Existing IDAS settings are preserved. Other product templates are disabled until
+you fill in their actual ME instance/token codes and set `enabled` to `true`.
+Additional products can be added using the same structure.
+
+To override the defaults for one product, add flags directly inside that product:
+
+```json
+"RTM": {
+  "enabled": true,
+  "run_session": false,
+  "run_token": true,
+  "me_instance": "",
+  "token": {
+    "market_code": "NATIONAL",
+    "product_type": "RTM",
+    "product_codes": "YOUR_ACTUAL_RTM_CODE"
+  }
+}
+```
+
+Remove a product's `run_session` or `run_token` key to inherit that common flag
+again. Explicit `false` overrides a common `true`; explicit `true` overrides a
+common `false`. Both false skips that product; `enabled: false` always skips it.
+Session timing overrides inherit any fields omitted from `setup.session`.
+Token timing settings belong to each product independently.
+
+Use `pytest tests\setup -s` to run all enabled products. Each product runs in its
+own browser: both flags true runs session then tokens in one login; otherwise
+only its enabled action runs. Test/report names include the product name.
+The session and token subfolder commands below select only products configured
+for session-only and token-only respectively; use the full setup command for a
+mixture of modes.
