User-facing docs (USER-GUIDE en+es, README en+es): - New short paragraph under §3.1 GUI noting the in-tool Help button on every detail page, what it contains (When to use / Steps / Examples / Tip), and that content lives in tools.<id>.help_md. - One-line note in the README tool tables pointing at the same. - Mention the sidebar +/- nav indicators replacing Streamlit's default Material Symbols chevron. Developer docs: - DEVELOPER: new "Tool page header" subsection documenting render_tool_header(tool_id), the help_md markdown skeleton, and the fallback to help.missing_body when a tool's help is absent. Update i18n authoring rules to list help.* keys and the per-tool help_md field alongside name/description/page_title/page_caption. - TECHNICAL: new §10c documenting the sidebar nav indicator swap — CSS in _HIDE_CHROME_CSS plus _SWAP_NAV_SECTION_INDICATOR_JS injected through the hide_streamlit_chrome() iframe bundle.
