robots.txt (sitemap pointer, /metrics and /scrape/ disallowed),
sitemap.xml (/ and /docs), and llms.txt (site + API summary for LLM

keywords, meta description, canonical, Open Graph/Twitter tags,
schema.org WebApplication JSON-LD, theme-color, and an inline SVG
favicon (also silences the /favicon.ico 404).
