[ConNext] Huisstijl (brand identity)

[rubenvdlinde]

Part of #23 (Epic).

Goal

Roll out the updated huisstijl across all surfaces: brand guide, design tokens, app UIs, documentation, drukwerk. The huisstijl is shared between ConNext (public product brand) and Conduction-the-company.

Source

• BRAND.md — wordmark, kleurpalet (incl. Nextcloud blue), typography, Apps-vs-Solutions terminology
• DESIGN.md — rationale (tone-shift MKB-direct, productbedrijf direction)
• brand/tokens.json — DTCG tokens

Scope

• Land foundation work on main: open PR feature/brand-2026 → main for BRAND.md / DESIGN.md / brand/tokens.json
• ConNext wordmark — pure typography: "Con" cobalt + "Next" Nextcloud-blue, "by Conduction" subtitle, Conduction-hexagon-avatar lockup. No icon.
• Color palette additions:
  • Nextcloud Blue #0082C9 (color.brand.nextcloud) — wordmark "Next", Nextcloud citations, kernel-hex on platform diagrams
  • Nextcloud Cyan #1CAFFF — gradient endpoint only
  • gradient.nextcloud — linear-gradient(45deg, #0082C9, #1CAFFF) for Nextcloud-kernel hex top-face
• "Next" markup convention — three places blue applies (wordmark, "Nextcloud" citation, idiomatic "next" referring to Nextcloud-as-platform); three places it does not (generic "next page", letter-strings within other words, decoration without brand-meaning)
• Roll updated tokens through nextcloud-vue and consuming apps
• Asset deliverables: SVG wordmarks (ConNext + Conduction), hexagon avatar, drukwerk templates

Out of scope

• Product positioning → Product proposition sub-issue
• Website implementation → Website sub-issue
