/**
 * Research & build data-layer test (dev tool, run with Node — no browser):
 *
 *   node dev/research-builds.test.mjs
 *
 * The player's progression loop has two halves — research (time-based,
 * one project at a time) and building (credits + minerals) — and the
 * command deck that will host them. The RULES are not implemented yet;
 * this test pins the data contract the future code will lean on:
 *   - the three config files are registered in data/manifest.json;
 *   - the rule knobs exist (timeUnit, maxConcurrent = 1, resources);
 *   - projects/builds are typed, empty maps (no content yet);
 *   - the `_template` entries document every required field;
 *   - the deck has exactly six slots in the right order.
