/* ===========================================================================
   MECHANIST enrol portal — student / employer facing design system
   ---------------------------------------------------------------------------
   Shared by every page an applicant, employer, parent or school rep sees:
   index, student_form, id_upload, success, capture_signature,
   capture_tp_signature, menu.

   MOBILE FIRST. These pages are mostly opened on a phone from an SMS link, so
   the base rules target a small screen and widen at breakpoints. Two details do
   the heavy lifting there:
     - every form control is >=16px, because iOS Safari auto-zooms the page when
       you focus an input smaller than that
     - interactive targets are >=44px tall (Apple's minimum touch target)

   Class names deliberately match what the pages already used, so switching a
   page over is mostly deleting its <style> block.
