/* =====================================================
   SahiHisab — Sidebar Redesign (index12 Sea Blue Theme)

   Design DNA from index12.html:
   · Plus Jakarta Sans 800 headings + DM Sans 500 body
   · Sea blue 9-shade palette (#062C4E → #E1F5FE)
   · --r: 14px radius, --sh-* shadow scale
   · Pill-shaped badges, gradient accent bars
   · Hover: translateY + scale + rotate micro-interactions
   · Glass overlays with rgba borders

   Uses body .selector specificity — NO !important.
   ===================================================== */
