/* ============================================================================
   orkastor.cloud — the tenant domain's front door.
   ============================================================================

   Design register follows the luxury layer already shipped on orkastor.com and
   kubegraf.io: one accent at ~5% of pixels, machined radii (never pills), a
   single grain overlay, one radial glow per section, asymmetric easing, and all
   metadata in neutral mono. Anti-patterns deliberately avoided: multiple coloured
   glows, gradient text everywhere, emoji icons, scale-up hovers, second-long fades.

   TWO HARD CONSTRAINTS THAT SHAPED THIS FILE, both from the platform design:

   1. NO COOKIES. NONE. Not analytics, not preferences, not a consent banner.
      This page is served from orkastor.cloud, and until that domain is on the
      Public Suffix List a cookie set here is scoped to the registrable domain —
      which means every tenant environment at <env>-<slug>-<hash>.orkastor.cloud
      would receive it, and could set one back. A marketing cookie on this host is
      a cross-tenant channel. There is no third-party script on this page for the
      same reason.

   2. NO CLAIM THAT OUTRUNS THE BUILD. gates §2.5 of the design docs: marketing
      copy is updated to match what exists, and NOT before it exists. So: no
      pricing (the rates are unmeasured and an earlier published set was 21% below
      cost), no uptime or SLA, no customer logos, no benchmark numbers. The status
      line is the same one orkastor.com already uses.

   Self-contained: system-stack fonts with the brand faces used when present, no
   webfont fetch, no build step. It is one HTML file and this stylesheet.
