   ⚡ QUICK GUIDE — CSS FILE SAMAJHNE KE LIYE ⚡
   ==========================================================================
   Ye file lambi hai magar sections mein bati hui hai. Har section ka header
   [SECTION NAME] jaisa likha hai — Ctrl+F se search kar lein.

   Kya kahan milega:
   - Colors/Font       -> neeche ":root {" wala hissa (sab se pehla block)
   - Navbar/Logo size  -> "Navbar" section -> .logo-img
   - Top image section -> "Scan-frame signature motif" + "Banner" section
   - About section     -> "About" section
   - Image Slider      -> "Slider" section
   - Services cards     -> "Services" section
   - FAQ box            -> "FAQ Accordion" section
   - Footer             -> "Footer" section
   - Contact page       -> "Contact Page" section
   - Mobile/tablet view -> sab se aakhir mein "Responsive" section

   Rang (color) badalna ho tu sirf ":root" ke andar --teal wali line badlein,
   pura website apne aap update ho jayega.
