/* ============================================================
   SZABUL — Online Attendance · Brand Theme
   Shaheed Zulfiqar Ali Bhutto University of Law, Karachi
   ------------------------------------------------------------
   Palette (from the university crest)
     Crest green   #00441F   primary / headers / buttons
     Leaf green    #0B6B38   hover / focus / accents
     Pressed green #06331A   active states
     Brass gold    #B28E40   hairline rules only (scales of justice)
     Paper         #F4F7F4   page background
     Ink           #1E2A22   body text
     Row tint      #F3F8F4   zebra rows
     Line          #D8E2DA   table / input borders
   Type
     Wordmark & headings : Georgia / Times New Roman (serif)
     Data & controls     : Segoe UI / Tahoma / Arial (sans)
   Notes
   - Selectors are prefixed with `body` so they outrank the
     legacy <style> blocks left in each page at equal cascade.
   - Row colours are NOT !important on purpose: code-behind
     still paints semantic rows (e.g. red = problem, green =
     present) via inline styles and must keep winning.
