## Markdown Instead of HTML

Every public page answers `Accept: text/markdown` with a markdown version of
that page — the same content, without the navigation, advertising and layout
markup. Every detail page returns its own record: blog posts, news, insight
reports, engineering articles, job listings, ship owner and manager profiles,
maritime company profiles with their open vacancies, suppliers, service
providers, ship agents, country directory hubs, knowledge-base answers and
categories, glossary definitions, maritime and merchant-navy guides, market
profiles, ports, vessels, machinery, parts and events. Section and listing
pages return this file. Send the header to the ordinary canonical URL; there
is no separate endpoint and no key. Company contact details are not included
in any representation.

## Questions and Answers

The knowledge base is https://marineinsight360.com/knowledge-base: maritime questions with a
direct answer paragraph first and the detail below it, each marked up as a
schema.org Question with an acceptedAnswer. The glossary at
https://marineinsight360.com/glossary defines maritime terms with a one-sentence definition
followed by a fuller one. Both are written to be quoted directly with
attribution to the canonical URL.
