Issue #1: Project scaffolding: SvelteKit + Tailwind + TypeScript

Status: COMPLETED Issue: #1 Branch: feature/issue-1-project-scaffolding

Summary

Initialize the SvelteKit project with Svelte 5 (runes mode), Tailwind CSS, TypeScript strict mode, proper directory structure, and ESLint + Prettier configuration.

Acceptance Criteria

• SvelteKit project initialized with Svelte 5 (runes mode)
• Tailwind CSS configured and working
• TypeScript strict mode enabled
• Directory structure: src/lib/, src/routes/, src/lib/components/
• ESLint + Prettier configured
• dev, build, preview, lint, format scripts in package.json

Implementation Phases

Phase 1: SvelteKit + TypeScript Initialization

Use the SvelteKit scaffolding tool (npx sv create) to create the project in the current directory with:

• SvelteKit with Svelte 5
• TypeScript strict mode
• Vite as the build tool

Since we're in an existing git repo with just a README, we'll scaffold into a temp directory and move files over.

Phase 2: Tailwind CSS Integration

Add Tailwind CSS v4 using the SvelteKit integration:

• Install @tailwindcss/vite and tailwindcss
• Configure the Vite plugin
• Add Tailwind CSS import to app.css

Phase 3: Directory Structure

Create the required directory structure:

• src/lib/ (SvelteKit default)
• src/lib/components/ — reusable UI components
• src/lib/services/ — API/service layer (for future issues)
• src/routes/ (SvelteKit default)

Phase 4: ESLint + Prettier

Configure ESLint and Prettier using the SvelteKit recommended setup:

• eslint + @eslint/js + eslint-plugin-svelte + typescript-eslint
• prettier + prettier-plugin-svelte
• Add lint and format scripts to package.json

Phase 5: Verify

• Run dev server to confirm it starts
• Run build to confirm production build works
• Run lint and format to confirm tooling works
• Verify TypeScript strict mode is active
