/* ==========================================================================
   Tanvir Creates — Portfolio Stylesheet
   Vanilla CSS, no build step. Design system: near-black / off-white surfaces
   with a single saturated red as the signature accent (glows, active states,
   icon marks, gradient CTA cards) — inspired by the Rentener Dribbble
   reference. Organized top to bottom:
   1. Reset & tokens (theme variables)
   2. Base/typography
   3. Layout utilities
   4. Components (nav, hero, cards, grids, forms, footer)
   5. Animations
   6. Responsive breakpoints
