Tagline: "Give it the work at dusk. Read it at dawn."

## Introduction

Hesper is a coding agent that works the night shift. Give it the backlog at the end of the day: tests to fix, a library to upgrade, docs to bring up to date. It works through them overnight and leaves reviewed pull requests to read in the morning.

Hesperus is the evening star, Venus, the first light to come out at dusk. The wordmark is hespər: the second e is the first e turned over, the way the evening turns into night. Said HES-pər, the turn is the name’s whole idea and the icon on its own.

Night and Venus cream carry the brand, with Dusk blue and an ember horizon for the hours in between.

## Marks

hespər is always written with its turned ə: never two plain e’s, never a capital H. Use the lockup (the ə tile, then the word) where the brand introduces itself; the wordmark alone in a navigation bar; the ə alone for the app icon, the profile picture and the favicon. In the terminal and in code, use the monospaced cut. Teach the turn once near the logo: hespər, said HES-pər.

## Colour

- **Night** #12141C: The ground: the website, signage and merchandise.
- **Venus** #F2E8C8: The evening star: the logo, headlines, the primary button.
- **Haze** #A7A9B8: Secondary text on Night: sub lines, captions, timestamps.
- **Dusk** #1F2E66: The blue hour: panels, cards, the sky behind the hero.
- **Ember** #E9784A: The last light on the horizon: status and the one warm accent.
- **Dawn** #F7F3EA: Paper and light pages: documents, docs in light mode, print.

## Type

- **Geist**: Headlines and text, as on the website: semibold 600 at 48 px with −1.2 px tracking for the hero line, medium 500 at 18 px for the sub line, regular for text. A plain grotesque that sits under the heavy custom wordmark without competing. By Vercel, SIL Open Font License 1.1, about 70 KB variable.
- **Geist Mono**: Tasks, times, branch names and the command line, where the monospaced cut of the logo also lives. By Vercel, SIL Open Font License 1.1.

## Voice

Hesper speaks like a trusted colleague on the night shift: brief, dry, exact. It reports what it did, what it didn’t, and why, and it leaves the decisions to the morning.

Evening and morning are the brand’s only images: dusk, dawn, the star. Never sleep jokes, never hustle.
