## Overview

A film-label system inspired by boxed editions. Cream card stock, spine-red accent, plate-numbered hierarchy.

## Colors

The palette is built around high-contrast neutrals and a single accent that drives interaction.

- **Primary (`#141210`):** Headlines and core text.
- **Secondary (`#6E6A60`):** Borders, captions, and metadata.
- **Tertiary (`#A6262B`):** The sole driver for interaction. Reserve it.
- **Neutral (`#EFE8D8`):** The page foundation.

## Typography

- **display:** EB Garamond 5.5rem
- **h1:** EB Garamond 2.6rem
- **body:** EB Garamond 1.05rem
- **label:** Inter 0.7rem

## Do's and Don'ts

- **Do** use Tertiary for exactly one action per screen.
- **Do** let Neutral carry the composition — negative space is a feature.
- **Don't** introduce gradients. This system is flat on purpose.
- **Don't** mix Tertiary with alternate accents; the single-accent rule is load-bearing.
