 ## Project Overview
 
-This repository contains reusable GitHub Actions workflows and composite actions (Astro, Vite, Lint/Format, Images) for the AREA44 ecosystem.
+This repository contains reusable GitHub Actions workflows and composite actions (Astro, Vite, Vite-Plus, Lint-Format, Images) for the AREA44 ecosystem.
 
 ## Core Directives
 
-- **ES Modules**: The project is configured as an ES module (`"type": "module"` in `package.json`). Build artifacts in `dist/` are also generated as ESM.
+- **Vite+ (vp)**: The project is managed by Vite+, providing unified tooling for package management, build, test, lint, and formatting.
+- **ES Modules**: The project is configured as an ES module (`"type": "module"` in `package.json`). Build artifacts in `dist/` are generated as ESM via `vp pack`.
 - **Tracked Build Artifacts**: The `dist/` folder is tracked in the repository to allow composite actions to be used directly without a build step in consuming workflows.
-- **Clean Distribution**: The `dist/` directory must only contain final bundled JavaScript files. Do not include source files or redundant artifacts.
-- **Compatibility**: Preserve original `action.yml` files in root directories (astro/, lint-format/, images/, vite/) and maintain original public inputs/outputs for backward compatibility.
-- **No Shared Chunks**: `rolldown.config.mjs` uses separate configurations for each entry point to prevent shared chunks that cause "require" errors in ESM-based GitHub Actions runners.
+- **Clean Distribution**: The `dist/` directory must only contain final bundled JavaScript output files. Do not include source files or redundant artifacts.
+- **Compatibility**: Preserve original `action.yml` files in root directories and maintain original public inputs/outputs for backward compatibility.
+- **Centralized Configuration**: All tool configurations (build, lint, test, format) are consolidated in `vite.config.ts`.
 
-## Development & Build
+## Development & Commands
 
-- **Build**: Use `npm run build` to bundle the project using Rolldown.
-- **Minification**: Output files are minified (`minify: true` in `rolldown.config.mjs`).
-- **Node.js**: The project uses Node 24 and targets the Node platform for bundling.
+- **Setup**: Run `vp install` to install dependencies and ensure local binaries are available.
+- **Build**: Use `vp pack` to bundle the project. Output files are minified and include an `eslint-disable` banner.
+- **Lint & Format**: Use `vp lint` and `vp fmt`. Formatting enforces sorted imports and mandatory curly braces for control flow.
+- **Unified Validation**: Use `vp check` (or `vp check --fix`) for pre-commit validation.
+- **Node.js**: The project uses Node 24. For GitHub Actions, set `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true` to address Node.js 20 deprecation warnings.
+- **Package Management**: Prioritize the `packageManager` field in `package.json`. Bun 1.2+ support favors `bun.lock` and excludes the deprecated `bun.lockb`.
 
 ## Testing
 
-- **Unit Tests**: Use Vitest for unit testing. Tests are located in `__tests__/`. Run them with `npm run test`.
-- **Integration Tests**: Integration tests are split into separate workflow files (`.github/workflows/`) to ensure isolated runs and avoid artifact name conflicts.
-- **Environment Detection**: Core environment detection logic is in `src/detect-env.ts`.
-- **Lint/Format Logic**: Core logic for running lint/format scripts is implemented directly in `lint-format/action.yml` using bash.
+- **Unit Tests**: Use Vitest (via `vp test`) for unit testing logic in `__tests__/`.
+- **Integration Tests**: Split into separate workflow files (e.g., `test-astro.yml`, `test-lint-format.yml`) to ensure isolated runs.
+- **Environment Detection**: Logic in `src/detect-env.ts` detects Node.js version (checking `.nvmrc`, `.node-version`, `engines`) and package manager.
+
+## GitHub Actions Logic
+
+- **Dynamic Environment Variables**: The Vite and Vite-Plus actions dynamically set `VITE_SITE_URL` and `BASE` based on the repository context (project site vs. user/org page).
+- **Images Action**: Optimizes media using standard tools (`svgo`, `optipng`, etc.) and supports WebP/AVIF conversion with automated system package installation.
+- **Autofix CI**: Integration with `autofix-ci/action@v1` requires the workflow name to be `autofix.ci` and the file to be `autofix.yml` or `autofix.ci.yml`.
 
 ## Coding Preferences
 
-- Use descriptive names for internal functions (e.g., `setOutputs`, `detectNodeVersion`) rather than generic names.
-- Always include an 'eslint-disable' banner in generated files via rolldown config.
+- **Naming**: Use descriptive names for internal functions (e.g., `setOutputs`) and variables (e.g., `error` instead of `err`) to satisfy strict linting.
+- **Formatting**: Import sorting is enforced by group (type, external, internal, etc.). Mandatory curly braces are required for all control flow statements.
