   Learnova Teach (teach.learnova.nz) — hand-written, zero-build.
   Same family as the student hub: warm paper + ink navy; product accents
   gold / rose / green; EB Garamond display, Inter body.
   Teach differences: workbench grammar — tabs, digest cards, roster table,
   grant switches. PC-first; narrow screens wrap, never scroll sideways.
