<?php
/**
 * Bloat — disable WordPress features site owners rarely use but every
 * frontend pays for in bytes / requests / attack surface.
 *
 * Each setting is a single toggle that adds (or doesn't add) one or
 * two filters. Per the SETTINGS.md standard, every toggle ships with a
 * label + description that names the actual ergonomic value.
 *
 * Six toggles, all opt-in (default false). The defaults are
 * conservative because every site has at least one plugin that quietly
 * depends on the surface this module strips — better to make the user
 * choose than to break themes on activation.
 *
 * Tier: Free (FEATURES.md "Others" §10-§15 — declared in commit
 * `4e36051` before this implementation).
 *
 * @package XSpeed
