Delete the static mirror; the terminal is the only page

[ledwards]

Follow-up to #123 and #127. Those made the mirror invisible to Google; this removes it.

Why

The static mirror existed to make an xterm.js terminal readable to crawlers, and it worked well enough to cause the problem it now has. Google indexed all 70-odd pages and started showing sitelinks under the root.vc result:

Root Ventures — Deep tech seed fund in San Francisco
About · Team · Jobs · Creator · Radical

That advertises a conventional website sitting behind the terminal. The terminal is the product, so the website goes.

What replaces it

js/terminal-ext.js already parsed the URL fragment as a command to run on load, so the addressing scheme was sitting there unused. /#tldr-chargelab now shows ChargeLab inside the terminal instead of on a page pretending not to be one.

• _redirects — every old mirror URL 301s to its command. Not a 404: a redirect tells Google to drop the indexed URL and fold its signals into the homepage, and an inbound link from someone else's site still lands on something real. Netlify :slug placeholders cover all 76 companies and the whole team in four rules.
• The homepage's offscreen block is now the only HTML copy of the portfolio and team, with deep links in place of paths.
• schema.org — Person and company nodes move into the homepage @graph, keyed by fragment @ids (#person-avidan, #company-chargelab) so each stays individually addressable to a parser.
• llms.txt / llms-full.txt point at deep links.
• The www command advertised /about/ and /portfolio/. Those now redirect back into the terminal, so it would have sent people in a circle — it points at llms.txt instead.
• css/pages.css is deleted; nothing renders from it any more.

What this gives up, deliberately

Long-tail search. Google strips fragments before indexing, so root.vc/#tldr-chargelab and root.vc/ are the same URL to it. root.vc can no longer rank for "root ventures chargelab" with a dedicated result — one page cannot hold 76 topics. Brand queries are unaffected, and consolidating everything into one URL concentrates authority there.

Per-company share cards. Open Graph tags are per-URL, so a deep link pasted into Slack renders the generic Root Ventures card.

Both are the cost of having exactly one indexed URL, which is the point of the change.

Hash parser

The parser split the fragment on every hyphen, so a hyphenated slug became two arguments — a company added as vibe-robotics would have broken its own deep link. Harmless while pages existed; not harmless when the fragment is the only address. It now splits on the first hyphen only.

Deep-link arrivals are also tracked now. Fragments fire no pageview of their own, so every arrival at a specific company was invisible in analytics.

Test plan

• npm test — 94/94 passing. The count drops from 313 because ~229 were it.each over the 76 mirror pages. New coverage for the redirect map (destinations, both URL forms, rule ordering, all 301), the homepage @graph, deep-link parsing including the hyphenated-slug case, and an assertion that no mirror path is emitted at all.
• npm run build — dist/ contains no about/, jobs/, portfolio/ or team/ directories
• Served the build and loaded /#tldr-chargelab in a browser: terminal boots with the command already run, photo URL correct
• Redirects need the deploy preview to verify — Netlify processes _redirects at the edge, not locally
