/**
 * Purpose: Shared Prettier configuration for all acamarata JS/TS packages.
 * Inputs: none — this file is consumed via the "prettier" field in package.json.
 * Outputs: a Prettier config object with base settings and per-file-type overrides.
 * Constraints: Prettier 3.x required (see peerDependencies). The overrides array
 *   is evaluated in order; later entries win on conflict.
 * SPORT: packages.md — @acamarata/prettier-config
