   Plain CSS, no frameworks. White + orange, warm and handcrafted.
   Organized by section:
     1. Font & custom properties
     2. Reset & base
     3. Utilities (skip link, visually-hidden, container, buttons)
     4. Header & navigation
     5. Hero (+ entrance animation, squiggle, scroll hint)
     6. Marquee strip
     7. Sections & cards
     8. Skills
     9. Footer / contact (inverted panel)
    10. Scroll-reveal (JS-enhanced)
    11. Reduced motion
   Verified WCAG 2.1 AA ratios (on white): ink 18.0 · muted 6.4 ·
   link orange #c2410c 5.2 · deep #9a3412 7.3. On dark footer #201409:
   cream 17.0 · orange #f97316 6.4. #ea580c (3.56) is used only for large
   text and non-text UI; #f97316 on white is decorative only.
