   Hari Chintha — Portfolio
   A grab-bag of "fancy dev portfolio" tricks, hand-rolled:
   - preloader (Awwwards-style % counter)
   - custom cursor that grows on hover (agency-site style)
   - animated gradient-mesh blobs + constellation canvas (Stripe/Linear-style hero)
   - floating glass pill nav w/ numbered links (Linear/Raycast + Brittany Chiang style)
   - infinite marquee ticker
   - spotlight-glow + 3D tilt cards (Aceternity-style)
   - magnetic + tactile "pressable" buttons (Josh Comeau-style)
   - scroll progress bar, back-to-top, grain overlay
