Hostwarden brand

The mark of Hostwarden: a tower whose courses are rack units, the warden over the hosts. One LED is lit, in signal yellow. Someone is watching.

Everything here is computed, not drawn. src/generate.py builds every file in svg/ and png/ from the tower's geometry and the font's outlines, and CI checks that the committed files are exactly what it writes. A variant that is missing is added to the generator, never made in an image editor, or the mark exists twice and the copies drift apart.

Which file where

• png/hostwarden-avatar-1024.png: the GitHub organization avatar. GitHub rounds the corners itself.
• png/hostwarden-social-preview.png: a repository's social preview (Settings → Social preview), 1280 × 640.
• svg/hostwarden-signet.svg: the mark on its petrol square.
• svg/hostwarden-signet-free.svg: the petrol tower without a ground, for light backgrounds; -invers is the frost tower for dark ones.
• svg/hostwarden-wordmark.svg: the word alone, in petrol; -invers in frost.
• svg/hostwarden-lockup.svg: tower and word side by side, for light backgrounds; -invers for dark ones. png/ has both at 1200 px.
• png/favicon-*.png, png/apple-touch-icon-180.png: browser tab and home screen.

The LED bezels are holes, not painted circles, so the marks without a ground show whatever they sit on.

Color

• Petrol #0C4A55: the mark on light grounds, the square, the social preview.
• Deep #072E36: dark grounds.
• Frost #ECF2F1: light grounds, the tower on petrol.
• Stone #A9BDBF: secondary text on petrol.
• Signal #F9A800: the lit LED and nothing else (RAL 1003).

Contrast: petrol on frost 8.7:1, frost on deep 12.8:1, stone on petrol 5.0:1, signal against petrol 5.0:1. Signal on frost is only 1.7:1, which is why the lit LED always sits in a petrol bezel and signal never carries text. Frost is a cool white on purpose; a warm cream would pull the mark toward other brands' palettes.

Type

Barlow Semi Condensed, Bold for the word and Medium for the social preview's lines, under the SIL Open Font License (src/fonts/OFL.txt). Barlow draws on California's highway signs, which suits a project about guardrails. The word is outlines, not set text, so no output file needs the font installed.

The name

In text the name is always Hostwarden, capitalized like any other proper noun, wherever it stands in a sentence or a title. Only the wordmark writes it in lower case, and so does anything that is spelled as an identifier: the command, a path, a repository (hostwarden/hostwarden). An image of the wordmark gets alt="Hostwarden".

The two follow different jobs. In a sentence the capital tells the reader that this is a name and not a common noun. The wordmark stands next to the tower, and there a capital H, two stems and a crossbar, repeats the tower's block and its courses, so the word starts with a second tower. The lower-case h has a single stem and leaves the tower to be the mark. It also matches what a user types.

Rules

• Clear space around every mark: a quarter of the tower's height.
• In the lockup the word stands on the tower's base line, its x-height 0.37 of the tower's height, 0.2 of that height apart.
• Smallest sizes: the signet 16 px, the lockup 120 px wide.
• Never recolor, stretch, rotate or outline the mark, and never light a second LED.
