| `HOST` | Server bind address | `127.0.0.1` |
| `PORT` | Server port | `3000` |
| `COOKIE_SECURE` | Enable HTTPS-only cookies | `false` |
| `LIBRARY_DISPLAY_MODE` | Public index layout: `inline` (stacked sections) or `nav` (filter buttons in header) | `inline` |

## Overview

A simple, self-hosted book tracker built with Rust. Highlights:
- Single Rust binary with embedded assets
- Password authentication with session cookies
- Track books across Read, Reading, and Want to Read
- Track books across Read, Reading, and Want to Read (labels customizable from admin)
- Google Books search to add titles with cover art and ISBN
- Library search from the admin page (title / author / ISBN)
- Toggle between inline category sections and a filter-nav layout via `LIBRARY_DISPLAY_MODE`
- Per-book notes
- JSON API for listing and fetching books
- SQLite for persistent storage

27	28		## Overview

29	30		A simple, self-hosted book tracker built with Rust. Highlights:
30	31		- Single Rust binary with embedded assets
31	32		- Password authentication with session cookies
32		-	- Track books across Read, Reading, and Want to Read
	33	+	- Track books across Read, Reading, and Want to Read (labels customizable from admin)
33	34		- Google Books search to add titles with cover art and ISBN
	35	+	- Library search from the admin page (title / author / ISBN)
	36	+	- Toggle between inline category sections and a filter-nav layout via `LIBRARY_DISPLAY_MODE`
34	37		- Per-book notes
35	38		- JSON API for listing and fetching books
36	39		- SQLite for persistent storage
