   Learnova student hub (student.learnova.nz) — hand-written, zero-build.
   Same family as the portal: warm paper + ink navy; product accents
   gold / rose / green; EB Garamond display, Inter body.
   Hub differences: denser dashboard type, card grammar for "do this now".
   PC-first: desktop layout; narrow screens only wrap, never scroll sideways.
