    return if FeatureFlag.enabled?(flodoc_feature_name)

    render json: { error: "Feature not available" }, status: :forbidden

<!-- app/javascript/tp_portal/components/FeatureFlagManager.vue -->
<template>
  <div class="feature-flag-manager">
    <h3>Feature Flags</h3>
    <div v-for="flag in flags" :key="flag.name" class="flag-item">
      <span>{{ flag.name }}</span>
      <Toggle
        :model-value="flag.enabled"

      />
    </div>
  </div>
</template>
```

      t.string :name, null: false, index: { unique: true }
      t.boolean :enabled, default: false
      t.timestamps
    end

    # Seed default flags
    FeatureFlag.create!(name: 'flodoc_cohorts', enabled: true)
