PR Summary

Medium Risk
Mostly documentation/UI changes, but it adds runtime file-system lookups to resolve GitHub source links and new client-side fetching for Markdown copy, which could affect rendering/performance or non-Node runtimes.

Overview
Refreshes the docs UX: new typography (local Season + Martian Mono), updated navbar/search/theme controls, a new global DocsFooter, and significant sidebar/TOC styling + separator icons.

Adds richer page actions by switching LLMCopyButton to copy raw Markdown via markdownUrl, introducing an Open popover (ViewOptionsPopover) with links (Markdown, GitHub source, and AI tools), and resolving per-page GitHub source URLs via server-side content path detection.

Reorganizes the docs IA (categorized meta.json with section separators) and expands/updates content across languages, including new block pages (Memory, Note, Thinking, Webhook (outbound)), plus new docs like Mailer and Tables, and refreshed Copilot/model/integration-count text.

Greptile Summary

This PR refreshes the Sim docs layout: it replaces Inter/Geist with Season + Martian Mono fonts, introduces a categorised sidebar with section icons and a neutral active-state palette, adds a ViewOptionsPopover that lets readers open a page in GitHub, copy its Markdown, or send it to various AI tools (ChatGPT, Claude, Cursor, Scira), and reorganises the sidebar navigation with translated section headings across all six locales.

Key changes:

• layout.tsx: swaps Google fonts for a local Season woff2 + Martian Mono; removes AnimatedBlocks.
• sidebar-components.tsx: refactors style constants; adds icon mapping for new section separators.
• All meta.json files: adds translated section separators (Basics, Core Concepts, Integrations, Security & Configuration, Execution & Operations, Deployment, Reference) and adds missing mailer/tables entries to non-English locales.
• page.tsx + components/ai/page-actions.tsx + components/page-actions.tsx: new ViewOptionsPopover and MarkdownCopyButton components; server-side resolveGitHubDocUrl resolves the source file on disk to produce a GitHub link.
• global.css: font variable references updated and several sidebar/code/navbar CSS tweaks.

Issues found:

• CONTENT_DOCS_DIR = join(process.cwd(), 'apps/docs/content/docs') will resolve to a non-existent path when Next.js runs from the apps/docs/ directory (the standard dev setup), causing the GitHub link to silently never appear in the popover.
• The module-level fetch cache in MarkdownCopyButton permanently stores rejected promises; a single failed network request prevents copy from ever working again without a page reload.
• global.css received extensive style edits, violating the project guideline to avoid this file in favour of component-local styles.
• Two relative imports (../../lib/cn, '../icons') bypass the @/ path alias convention used everywhere else.

Confidence Score: 4/5

• Safe to merge after fixing the CONTENT_DOCS_DIR path; the rest of the layout and categorisation changes are solid.
• The docs layout refresh and sidebar categorisation work well. Two logic issues need attention: the wrong process.cwd() prefix silently breaks the GitHub link, and the fetch cache can trap rejected promises. Both are confined to the new ViewOptionsPopover feature and don't affect the primary docs reading experience. The style/import issues are minor. A one-line path fix and a cache-eviction guard would clear all P1 concerns.
• apps/docs/app/[lang]/[[...slug]]/page.tsx (CONTENT_DOCS_DIR path), apps/docs/components/ai/page-actions.tsx (rejected-promise cache)

Important Files Changed

Filename	Overview
apps/docs/app/[lang]/[[...slug]]/page.tsx	Adds ViewOptionsPopover with GitHub/AI links; CONTENT_DOCS_DIR path likely wrong (doubles apps/docs prefix), silently breaking the GitHub link; minor indentation inconsistency on second popover block.
apps/docs/components/ai/page-actions.tsx	New MarkdownCopyButton and ViewOptionsPopover components; module-level fetch cache permanently stores rejected promises, preventing retry after a failed network request.
apps/docs/app/global.css	Extensive style updates (font references geist→season/martianMono, sidebar colors, hover/active states, code block styling); violates the guideline to avoid editing globals.css unless necessary.
apps/docs/components/ui/popover.tsx	New Radix-based Popover wrapper; uses a relative ../../lib/cn import instead of the @/lib/cn path alias used project-wide.
apps/docs/components/navbar/navbar.tsx	Adds Discord and Mothership CTA buttons, replaces "Mothership" nav tab with "Changelog"; uses a relative '../icons' import instead of @/components/icons.
apps/docs/app/[lang]/layout.tsx	Switches fonts from Inter/Geist Mono to Season (local) / Martian Mono; removes AnimatedBlocks; correctly applies new font CSS variables to html and body.
apps/docs/components/docs-layout/sidebar-components.tsx	Refactors sidebar item/folder styles to shared cn constants; adds per-section icons mapped from the new separator labels; neutral color palette replaces previous emerald accents.
apps/docs/content/docs/en/meta.json	Adds labeled section separators (Basics, Core Concepts, Integrations, Security & Configuration, Execution & Operations, Deployment, Reference) and moves quick-reference to the Reference section.
