/**
 * Named fault profiles. Each profile is a small function that returns an
 * array of FaultRule, expressing operator knowledge ("S3 is bursty",
 * "the auth service is slow") that would otherwise live as ad-hoc
 * probability numbers in every consumer's chaos config.
 *
 * Profiles are intentionally simple to compose:
 *
 *   import { chaos, profiles } from "chaosbringer";
 *
 *   await chaos({
 *     baseUrl: "http://localhost:3000",
 *     faultInjection: [
 *       ...profiles.flakyThirdPartyCdn(/cdn\.example\.com/),
 *       ...profiles.s3FivexxBurst(/s3\.amazonaws\.com/),
 *     ],
 *   });
 *
 * The numeric knobs in each profile are starting points based on what the
 * lab has seen produce useful failures. Override anything by passing a
 * second `options` argument; consumers who need a wholly different shape
 * should compose `faults.*` directly instead.
