+#!/bin/bash
+
+# validate-translations.sh
+# 
+# This script validates the structure of JSON translation files by comparing them 
+# against the reference English translation file (ui/src/i18n/en.json).
+#
+# The script performs the following validations:
+# 1. JSON syntax validation using jq
+# 2. Structural validation - ensures all keys from English file are present
+# 3. Reports missing keys (translation incomplete)
+# 4. Reports extra keys (keys not in English reference, possibly deprecated)
+# 5. Emits GitHub Actions annotations for CI/CD integration
+#
+# Usage:
+#   ./validate-translations.sh
+#
+# Environment Variables:
+#   EN_FILE          - Path to reference English file (default: ui/src/i18n/en.json)
+#   TRANSLATION_DIR  - Directory containing translation files (default: resources/i18n)
+#
+# Exit codes:
+#   0 - All translations are valid
+#   1 - One or more translations have structural issues
+#
+# GitHub Actions Integration:
+#   The script outputs GitHub Actions annotations using ::error and ::warning
+#   format that will be displayed in PR checks and workflow summaries.
