vitest.bench.config.ts

/**
 * Root-level config for benchmarks across all libs.
 *
 * Naming convention: shape is encoded in the filename so each glob is
 * unambiguous and the configs stay self-documenting.
 *
 *   - `*.micro.bench.ts`    → Shape A: vitest `bench()` microbenches.
 *     Run via `pnpm bench:micro` (`vitest bench --run`).
 *   - `*.scenario.bench.ts` → Shape C: vitest `it()` + assertions +
 *     `console.table`. Run via `pnpm bench:scenarios` (`vitest run`).
 *   - Plain `*.ts` under `libs/<lib>/scripts/` → Shape B: standalone
 *     tsx scripts. Not picked up by vitest; run directly with `tsx`.
 *
 * Both flavors live under `libs/<lib>/bench/` and share the workspace
 * aliases from the root `vite.config.ts`.
