# Example: Pod Volumes for Browser Tests
# Patterns: pod.volumes, volumeMounts, emptyDir, /dev/shm
# What this demonstrates: Browser-based tests (Cypress, Playwright) need
#                       /dev/shm sized appropriately. This shows how to
#                       mount a custom-sized shared memory volume via
#                       spec.pod.volumes and container.volumeMounts.
