Settings API (admin options)

Use this file when adding settings pages or storing user-configurable options.

Core APIs:

• register_setting()
• add_settings_section()
• add_settings_field()

• Register settings: https://developer.wordpress.org/plugins/settings/registration/
• Add settings fields: https://developer.wordpress.org/plugins/settings/settings-fields/

Practical guardrails:

• Use sanitize_callback to validate/sanitize data.
• Use capability checks (commonly manage_options) for settings screens and saves.
• Escape values on output (esc_attr, esc_html, etc.).
