The Source view exposed basic code editing but gave new LaTeX users little help making common changes. It now provides selection-aware bold/italic tools, heading/list/equation/footnote insertion with editable placeholders, common-command suggestions, comment toggling, paired delimiters and bracket matching, and line/column/selection status.

A live heading outline, an inline editing guide, an expanded workspace, and a Build PDF action beside the source controls make the edit-and-check workflow easier to discover. Insertions remain undoable and use the existing source/draft/save flow; editing remains guarded during saves, builds, recovery, and IME composition. The outline is intentionally bounded to 200 conventional single-line headings. Added the source editing guide and refreshed production dependency notices for the pinned CodeMirror autocomplete package.

Validation:

  • Frontend production build and lint passed.
  • All 130 Playwright tests passed across desktop and mobile, including new formatting, insertion, completion, escaped-delimiter, outline, help, focus, and busy-state coverage; existing Unicode, draft recovery, saved-version, diagnostics, and near-2 MiB editing workflows passed.
  • All 113 backend tests passed with real PDF conversions enabled, with no skips: mvnw.cmd verify -Ddoc2tex.test-pdf=true.
  • Inspected desktop and mobile editor screenshots; no page overflow.

Review follow-up:

  • Fixed the literal-environment ending check to allow trailing comments while still requiring the matching environment name. Regression coverage exercises all six supported literal environments and navigation to later headings.
  • Verified that escaped percent signs were already handled by skipping escaped characters before comment detection. Added regression coverage for escaped percentages, nested titles, escaped braces, consecutive backslashes, and actual unescaped comments; no change to the title parser was needed.
  • Both original review threads are resolved. CodeRabbit completed its follow-up review of commit 50f6d84 with no actionable comments.
  • Windows/Linux CI passed, including browser tests, real PDF conversions, the no-skipped-regressions gate, and Windows packaged launch/conversion/replacement/uninstall verification.

Inline comments:
Review comments at @frontend/src/latexEditing.ts:
- Line 68: Update the literal-environment ending check in the code around
`literal` so it recognizes an `\end{...}` command followed by an optional
trailing comment, such as `% example`. Clear `literal` for that line so
subsequent headings are included in the outline.
- Line 78: Update the title-parsing percent check so only an unescaped percent
sign ends parsing; preserve escaped percent signs such as `\%` and continue
parsing through the closing brace.
