+      # This CI supports skipping flaky or broken tests via GitHub repository variables.
+      # This allows quick fixes without code changes when tests break due to external factors.
+      #
+      # HOW TO SKIP TESTS:
+      # 1. Go to: Settings → Secrets and variables → Actions → Variables
+      # 2. Create or edit Repository variables:
+      #    - SKIP_TESTS_<PRODUCT>: Skip patterns for any product (uppercase)
+      #    - SKIP_TESTS_ALL: Skip patterns applied to ALL products
+      #
+      # PATTERN SYNTAX:
+      # - Single test: TestAccServer_Basic
+      # - Multiple tests: TestAccServer_Basic|TestAccServer_Other
+      # - Wildcard: TestAccServer.*
+      # - Contains: .*IPAM.*
+      #
+      # EXAMPLE:
+      # Variable: SKIP_TESTS_BAREMETAL
+      # Value: TestAccServer_Basic|TestAccServer_WithIPAMPrivateNetwork
