   IT SUPPORT SERVICES — "Support that actually shows up." (prefix: itx-)
   UNIQUE PRESENTATION — nothing here mirrors other pages:
       · dispatch-board hero: live ticket queue, status pills cycling states
       · ticket pipeline columns (Reported / Diagnosing / Resolved)
       · on-call rota board: week × shift grid + escalation chain
       · network topology map: pulsing packets travelling SVG links
       · post-mortem case cards (dl layout, time-to-fix accents)
       · ticket-stub CTA with perforated divider + admit counterfoil
   LIGHT / DARK MIX: hero DARK (house rule) then light pipeline,
   dark rota, light topology, dark post-mortems, light CTA stub.
   Light bands use dark ink #17093C + deepened accents.
   Palette on theme: navy #080A2B · magenta #B217BA · violet #7B2FF7
   · blue #2A7BFF · cyan #43D2E0 · gold #F0A400 · Afacad (global).
