docs(wiki): a signpost Home page and a curated sidebar Home was still the auto-generated one-line stub, which reads as abandoned to the one visitor the wiki actually gets: someone already on the repo who clicked the Wiki tab. It cannot be deleted - GitHub recreates it as the wiki's landing page - so the choice was only ever what it says. It now carries: what this wiki is and how it relates to gps.csutil.com/blog, an explicit drafts warning (GitHub hides the status field, so a visitor cannot otherwise tell these are drafts), four entry points chosen by reader intent rather than by topic, and where to send a correction. _Sidebar.md puts six themed groups on every page. Deliberately a subset - eighteen of thirty - since GitHub's own page list already enumerates everything; what it cannot do is say where to start. Sized at one screen each on purpose: GitHub serves this wiki with x-robots-tag: none, so it earns no search traffic and is worth investing in only for readers who are already here. Search indexing needs 500+ stars per GitHub's documented rule; this repo has 2.
