Hamac — brand

The visual identity of Hamac: logo files, their generator, the brand charter, and the funding marks every public Hamac material must carry. This repository is the source of truth. Other repositories (Hamac itself, documentation, slides) keep copies of the files they need and record which commit of this repository they came from.

The charter itself, charte-hamac.pdf, is written in French. It is built by CI, published to the forge's package registry (https://forge.ocamlpro.com/OSS/-/packages/generic/hamac-brand/latest), and locally with make.

Using the logo

Pick a file from logo/:

File	Use
hamac-logo-horizontal-{clair,sombre}.{svg,png}	default: headers, banners, slides — clair on light backgrounds, sombre on dark ones
hamac-logo-vertical-*.svg	square or tall formats: covers, posters
hamac-symbole-*.svg	the symbol alone, when the name is already written next to it or space is short: favicon, icon
*-mono-noir, *-mono-blanc	single-colour printing, engraving
hamac-avatar-512.png	forge, GitHub and social avatars

Do not redraw, recolour, stretch or rotate the logo; the charter lists what is allowed. The name is written Hamac; the command and packages stay lowercase (hamac, hamac-manifest).

Use of the name and logo is governed by the trademark policy.

Layout

Path	Content
logo/	ready-to-use files, versioned — no tool needed to use them
_src/	generator: gen_symbole.py (symbol geometry, every colour variant), _logo.typ (symbol + name, letters outlined), _avatar.typ, build-logos.sh
_palette.typ	the palette, single source for the charter and every Typst material
charte-hamac.typ	the brand charter (French)
fonts/	Nunito ExtraBold (SIL OFL 1.1), used only to regenerate the logos
financement/	France 2030, France Relance, NextGenerationEU and Cap Digital marks, with their provenance and usage rules
exploration/	design history: rejected directions and comparison sheets. The .typ sources there are kept as records and are not built

Rebuilding

make logos    # python3 + typst ≥ 0.15
make check    # logo/ must be exactly what _src/ produces; no typst warning
make          # charte-hamac.pdf
