The HIG crawler used to derive the `platforms: [...]` frontmatter +
`> **Platforms:** ...` body line from substring matching the whole
HTML for platform tokens. Every HIG page's nav/footer mentions all
5 platforms, so every page reported all 5 regardless of topic. The
`.md` files claimed `Designing for watchOS` is available on iOS /
macOS / tvOS / visionOS too — contradicting both the page's own
content and the post-#1073 schema fix.
The cupertino-side fix lands in mihaelamj/cupertino#1078: new
`HIGPlatformRules` foundation-tier table unifies crawler, indexer
strategy, and SQL backfill. This corpus commit rewrites the existing
.md files for the 10 platform-specific HIG topics:
- designing-for-watchos, watch-faces → watchOS only
- designing-for-tvos → tvOS only
- designing-for-visionos, spatial-layout → visionOS only
- designing-for-macos → macOS only
- mac-catalyst → iOS + macOS
- carplay, designing-for-ipados, designing-for-ios → iOS only
Cross-platform topics (the other 163 pages: buttons, alerts,
accessibility, etc.) are unchanged.
