Rewrites the pages that survive the restructure so they lead with what a reader
can accomplish, and points them at the sections added in the previous commit.
Page set and navigation are unchanged here; only content moves.
Keeps the skill count in README. CLAUDE.md's catalog-maintenance rule requires
the count to live in README and CLAUDE.md, and both now agree with the 19
directories under skills/.
Adds honest Hyperframes vs Remotion comparison: README section with
paragraph + table + open-source-vs-source-available callout, plus a
full guide at docs/guides/hyperframes-vs-remotion.mdx walking through
the core React-vs-HTML decision, practical differences (including a
GSAP side-by-side), and licensing.
Closes#318
