- Move the Tauri app (React frontend + Rust backend) into desktop/ via git mv — configs unchanged (relative paths: tauri.conf.json, vite.config.ts) - Root package.json becomes a private bun workspace container with orchestration scripts; desktop package renamed gridline-desktop - Scaffold www/ with Astro 7 + Tailwind v4 (hand-wired vite plugin, static output, ready for Dokploy) - Update release.yml for the new layout: projectPath: desktop, desktop/src-tauri resource paths, rust-cache workspace path - Update README + AGENTS.md structure trees and dev commands - Verified: vitest (1074), cargo test (354), desktop build, tauri dev (window launches), tauri build (dmg + app bundles), Astro build
