# Implementation Plan

## Project Constraints
- [x] Pure Go binary (no external system dependencies for PDF).
- [x] Config via `config.yaml` only (no CLI flags).
- [x] Hardcoded paths: `./content` (input), `./output` (build artifacts).
- [x] Modes: `gocv` (CLI), `gocv serve` (Daemon).
- [ ] Commit at every loop iteration. Do not push. Do not tag.

## Current Status
- [x] Project backbone exists (HTTP server, graceful shutdown, config reading).
- [x] Markdown parsing logic implemented (using goldmark).
- [x] HTML Template engine integrated (Hugo-like theme selection).
- [ ] PDF Generation implemented (Pure Go library selected and integrated).
- [x] CLI Mode (`gocv`) generates static files to `./output` and exits.
- [ ] Serve Mode (`gocv serve`) hosts HTML and serves PDF on demand.
- [ ] File Watcher implemented for live reload in Serve Mode.
- [ ] Dockerfile created for multi-stage build.

## Active Task
- [x] Analyze existing backbone code and integrate Markdown parsing.
- [x] Integrate HTML template engine with theme selection.
- [ ] Implement Serve Mode with file watching for live reload.

## Known Issues / Blockers
- [ ] Identify best Pure Go PDF library that supports HTML/CSS (or define CSS subset).
- [x] Current output is raw HTML fragments without full HTML document structure.

## Completed Log
- [x] Initial project structure defined.
- [x] Basic HTTP server and signal handling implemented.
- [x] CLI mode vs Serve mode distinction implemented (checks os.Args[1] for "serve").
- [x] Content reading from `./content` directory implemented.
- [x] Markdown to HTML conversion using goldmark library.
- [x] Theme system with templates/themes/{theme}/base.html structure.
- [x] Config.yaml theme setting (defaults to "default").
- [x] Output now generates complete HTML documents with styling.
