 - [ ] **Step 2: Verify the services-list CSS classes are in the built output**
 
-Run: `grep -c "services-list__heading" static/dist/theme.css`
+The build unwraps CSS-nesting `&__heading` into `__heading.services-list` (no literal `.services-list__heading` is emitted). Use a fixed-string search that matches the un-nested form:
-Expected: `1` or more (the class should appear in the built CSS).
+
+```bash
+grep -cF "services-list__heading" static/dist/theme.css
+```
+
+Expected: `1` or more. (Note: on Windows Git-Bash, prefer `grep -F` because POSIX `\\:` escapes are stripped before reaching grep.)
 
 - [ ] **Step 3: Verify the dynamic grid classes are in the built output**
 
-Run: `grep -E "lg\\\\:grid-cols-(2|3|4) " static/dist/theme.css | wc -l`
+Same Windows-shell caveat. Use fixed-string search:
-Expected: `3` (all three column counts should be present).
+
+```bash
+grep -cF "lg\:grid-cols-2" static/dist/theme.css
+grep -cF "lg\:grid-cols-3" static/dist/theme.css
+grep -cF "lg\:grid-cols-4" static/dist/theme.css
