Summary

Public Markdown gains recognizable link destinations and readable code snippets, and BlockNote's Paragraph menu stays open when focus moves into its options.

• Add favicons to ordinary internal/external links in public content and admin previews, with safe text-only fallbacks and hover-only underlines.
• Add PowerShell/ps1 highlighting and custom One Light/One Dark Pro palettes with matching bold-token rules.
• Keep code bodies and headers transparent. Every code block has an independent word-wrap toggle and equally sized icon-only wrap/copy controls with hover and keyboard-focus tooltips. Copy preserves the original source.
• Forward the Select portal container so partial text selections can be converted to headings with the pointer or keyboard.
• Update the changelog and architecture/product guides, and stabilize the related regression checks and PowerShell browser prebundling.

Rollout scope since v1.1.0

The release baseline is v1.1.0. The Markdown changes above are introduced by this PR. The updated Unreleased notes also include changes already merged into main since that release:

• #141: tsrs 0.23.0-ts7.1.0-beta.
• #142: oRPC 2.0.0-beta.49.
• #143: generated name-based avatars for accounts without an image.

Validation

• Scoped vp check on changed source, tests, styles, configuration, and documentation: passed.
• Web unit tests: 92 passed across 11 files, covering public rendering/highlighting and SSR hydration, editorial previews and saves, README import, collection search recovery, and avatars (--maxWorkers 2).
• Chromium tests/browser/about.browser.tsx: 5 passed, covering synthetic light/mobile and dark/desktop fixtures, saving through the real editor, and pointer/keyboard heading changes from partial selections.
• API tests/openapi-mapping.test.ts: 68 passed against the updated oRPC dependencies.
• Web vp build and API vp run --filter server build: passed.
• React Doctor: 97/100, with one advisory no-transition-all warning for the requested 300 ms Markdown link hover transition.

Validation is scoped; the full repository suite and database/provider-dependent acceptance tests were not run.

Deployment

• Changes since v1.1.0 add no database migrations or environment variables, and stored Markdown needs no migration.
• External favicons use Google S2 with only the destination hostname and no-referrer; failed image loads leave links usable.
• After merge, publish through the existing Publish Docker images workflow using the chosen version tag or manual dispatch, then deploy matching web/API revisions.

Summary by CodeRabbit

• New Features
  • Markdown links now display favicons for eligible internal and external destinations, with a fallback when a favicon cannot load.
  • Code blocks support PowerShell highlighting and an optional word-wrap toggle. Copying code preserves its original formatting.
  • Code blocks feature updated light and dark syntax highlighting; Markdown links gain hover underlines.
• Bug Fixes
  • Fixed issues with the block-style menu and avatars for missing images.
• Documentation
  • Added upgrade guidance covering matching API and web revisions, migration and environment-variable requirements, and external favicon fallback behavior.

Walkthrough

This PR updates public Markdown link rendering and code blocks, adds light and dark Shiki themes with PowerShell support, and forwards a portal container through SelectContent. It also adds tests and documentation for these changes and a browser test for partial-selection heading conversion.

Changes

Public Markdown rendering

Layer / File(s)	Summary
Markdown link favicons apps/web/src/components/public-content/content-link.tsx, apps/web/src/components/public-content/index.tsx, apps/web/tests/admin-blog-editor.test.tsx, apps/web/tests/public-content.test.tsx, docs/architecture.md, CHANGELOG.md	Eligible internal and external links display favicons. Failed favicon loads hide the image while keeping the link. Tests and documentation cover excluded link types and link behavior.
Code highlighting themes and languages apps/web/src/utils/shiki.bundle.ts, apps/web/src/features/public-content/prepare.server.ts, apps/web/src/styles.css, apps/web/tests/public-content-prepare.test.ts, apps/web/vitest.config.ts, docs/architecture.md, docs/prd.md, CHANGELOG.md	The Shiki bundle adds light and dark code-block themes and PowerShell support with the ps1 alias. Public highlighting uses the configured themes. Tests cover theme colors, bold tokens, and PowerShell tokenization.
Code-block wrapping and copy controls apps/web/src/components/public-content/code-block.tsx, apps/web/tests/blog.test.tsx, apps/web/tests/public-content.test.tsx	Public code blocks add a word-wrap toggle and tooltip-wrapped icon controls. Wrapping starts disabled and does not change the copied source. Tests cover copy feedback and preserved whitespace.

Editor block-style menu

Layer / File(s)	Summary
Portal container and heading selection packages/ui/src/components/select.tsx, apps/web/tests/browser/about.browser.tsx, CHANGELOG.md	SelectContent accepts and forwards an optional portal container. Browser tests cover converting a partial text selection to a heading by pointer or keyboard. The changelog also documents the name-based avatar behavior.

Full details: Title check

Explanation

The title "feat: improve Markdown links, code blocks, and editor formatting" names the three main areas of the changeset. The raw summary and objectives confirm changes to Markdown link favicons and hover underlines, code block theming, wrap and copy controls, and the BlockNote block-style menu fix in the editor. The title is broad, but it refers to real and central parts of the change, so it is related to the main change. It is a conventional-commit style title, under 70 characters, and it contains no file lists or vague terms.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 12 files. (4 skipped: 4 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
