Mirrors the index.html hero treatment across devkits, consultancy,
videos (dark strokes) and opensource (white strokes on dark bg).
.page-hero gets position:relative/overflow:hidden to contain them.

Complete rebuild: white/black palette, Hanken Grotesk + JetBrains Mono
typography, shared style.css, and five separate pages (index, devkits,
opensource, consultancy, videos). Real product content, pricing, and
video elements with replaceable src paths throughout. Removes old
v1/v2/lazy video experiments.
