/* =========================
   SUBJECTS PAGE
   Brought in line with dashboard.css/admin.css and quizzes.css:
   labeled form fields instead of a bare input row, a quieter card
   hover (no more heavy translateY(-3px) lift), and a muted delete
   button instead of solid red — same institutional tone as the
   rest of the admin section.

   Classes here are namespaced (subject-form-grid, subject-form-
   field, subject-add-btn, ...) rather than reusing quizzes.css's
   bare .form-field / .form-field-wide — both stylesheets load
   together in the SPA, so identical bare class names would create
   the same cross-page collision problem documented elsewhere in
   this project.
