// ── Branding (BRAND_*) ─────────────────────────────────────────────────────
//
// Single source of instance branding. Reads BRAND_* env vars once at startup,
// with Runic Gateway defaults, so any instance substitutes its own identity
// without a rebuild (the app ships as one prebuilt image).
//
// How it reaches the UI:
//   • Text + colors + asset paths are surfaced to the SPA through the public
//     settings API (settings.model.getPublic → SiteContext). The two fields the
//     admin can edit (site title, contact email) override these defaults.
//   • The static index.html shell (title/description/OG/favicon) is templated by
//     Express at serve time (see src/app.js).
//   • Server-side consumers (emails, TOTP issuer, API docs) read this directly.
//
// Image assets are delivered from the /brand mount (BRAND_LOGO/HERO/FAVICON), or
// any absolute URL. Runic Gateway ships neutral defaults baked into the image so
// an instance with no BRAND_* set still renders.

  // this instance is for is the operator's to say, through these two vars or an
  // installed module (MODULE_SYSTEM.md §2.7.1, slice 4). Every real instance
  // overrides both — `.env.uomysticmoon.example` sets its own wording — so these
  // are what an unconfigured instance shows, not what anyone ships.
