/**
 * Heroku-specific sensitive field patterns
 *
 * Consolidated list of field names and patterns that contain sensitive data in Heroku applications.
 *
 * Use this preset to ensure consistent PII handling across Heroku services.
 *
 * @example
 * ```typescript
 * import { HEROKU_FIELDS } from '@heroku/js-blanket/core/presets';
 * import { Scrubber } from '@heroku/js-blanket';
 *
 * const scrubber = new Scrubber({ fields: HEROKU_FIELDS });
 * const result = scrubber.scrub(data);
 * ```

/**
 * GDPR-relevant PII field patterns

 * Field names that typically contain personally identifiable information (PII)
 * regulated by GDPR (General Data Protection Regulation).
 *
 * Use this preset when handling EU user data to ensure compliance with GDPR requirements.
 *
 * @see {@link https://gdpr.eu/what-is-gdpr/|GDPR Official Documentation}
 *
 * @example
 * ```typescript
 * import { GDPR_FIELDS, HEROKU_FIELDS } from '@heroku/js-blanket/core/presets';
 * import { Scrubber } from '@heroku/js-blanket';
 *
 * // Combine multiple presets
 * const scrubber = new Scrubber({

/**
 * PCI-DSS relevant field patterns
 *
 * Field names that typically contain payment card information regulated by
 * PCI-DSS (Payment Card Industry Data Security Standard).
 *
 * Use this preset when handling payment card data to help maintain PCI-DSS compliance.
 *
 * **Important**: This preset helps reduce exposure of sensitive payment data in logs and
 * error reports, but is not a substitute for full PCI-DSS compliance measures.
 *
 * @see {@link https://www.pcisecuritystandards.org/|PCI Security Standards Council}
 *
 * @example
 * ```typescript
 * import { PCI_FIELDS } from '@heroku/js-blanket/core/presets';
 * import { Scrubber } from '@heroku/js-blanket';
 *
 * const scrubber = new Scrubber({
 *   fields: PCI_FIELDS,
 *   patterns: [/\d{4}-\d{4}-\d{4}-\d{4}/g]  // Also scrub card numbers in text
 * });
 * ```
