   P4 Study Lab
   Design read: an auth + progress web app for a single research programme,
   read as a focused study console. Native CSS tokens, one locked accent
   (heat amber), one radius system, one theme per page.

   Locks
     accent   : heat amber, used everywhere for progress / active / primary
     radius   : 10px for cards, inputs, buttons. 999px only for badges, avatars
                and progress tracks (documented exceptions, used consistently)
     theme    : single theme per render, toggled globally, never per section
     type     : Space Grotesk (display) / IBM Plex Sans (body) / IBM Plex Mono (data)
