From 1fc74b3ab865bce4e4c67c62128f6e8f5191f871 Mon Sep 17 00:00:00 2001 From: Masao Kitamura Date: Thu, 1 Oct 2026 16:56:41 -0700 Subject: [PATCH] Adopt the engineering practices: CI, checks, hooks and feature layout Add the pnpm verify gate with typecheck, lint, format, repository checks, tests, build and smoke, and the CI workflow that runs the same commands. Move the starting page into src/features/home behind a thin route file, enforce the layer boundaries in lint, pin Node 24 in .nvmrc and document the rules in docs/.
