Write Landing Docs

Public website documentation is authored under docs/**.
Read the Voice & Content section of ../../../DESIGN.md before drafting.
For docs/self-hosting/**, read Default Audience.
Verify claims, defaults, commands, limitations, and rollback behavior from current code.
Prefer one canonical page, a recommended path, short executable steps, and a visible verification result. Keep English and Simplified Chinese versions aligned.
If a published path changes, update internal links and add a tested permanent redirect in the landing repository that preserves locale prefixes and query parameters.
Run the focused documentation check for every changed page.

For docs/changelog/**, use ../docs-changelog/SKILL.md instead.
