- Parse `obsitex` YAML codeblocks (`eq-prefix: S` or `- eq-prefix: S`) using Obsidian's `parseYaml` API.
- Inject document-level `eq-prefix` into equation tags rendered in Live Preview, Reading View, and PDF export.
- Support prefixed ID generation (`% id: eq-S-xxxx`) for newly auto-generated equation tags.
- Update equation ID regex patterns (`/eq-[\w.-]+/`) to support dots in prefixes.
- Register hidden `obsitex` markdown codeblock processor and CSS rules (`.block-language-obsitex`) to hide instructions across views.
- Implement `FileIO.read()` across `ActiveNoteIO` and `NonActiveNoteIO`.
- Add unit tests for `obsitex` config parsing and `getEqNumberPrefix`.
- Add user-facing and architectural documentation in `docs/features/equations.md` and `docs/configuration/settings.md`.
- Implement `Clean Inline Double Dollar Symbols` text transform snippet.
- Convert inline double dollar signs `$$` to single dollar sign `$`.
- Keep block/display equation dollar signs (`$$`) intact (e.g. multi-line blocks or single-line equations starting/ending with `$$`).
- Add unit tests in `test_helpers/transforms.test.ts` to verify behavior.
- Update documentation in `docs/features/snippets.md` to document the new and existing double-dollar cleanup transforms.
- Extracted 214 TeX libraries, packages, core formats, and WebAssembly binaries from monolithic `tikzjax.js` into local `tikzjax-assets/` folder.
- Replaced monolithic 7MB runtime JS asset download from GitHub with a lightweight loader and Web Worker compilation engine.
- Implemented `tikzjax.worker.ts` to execute the TeX engine in a background Web Worker thread using modern Web standard APIs, preventing main-thread UI locks.
- Implemented `TikzJaxLoader` to parse code block preambles, lazily load/decompress assets synchronously via native `zlib`, cache core buffers in memory, and compile diagrams via the worker.
- Refactored `renderer.ts` and `live-preview-overlay.ts` to utilize the async loader, removing DOM-polluting `<script>` tags, global mutation observers, and custom window hooks.
- Swapped unsafe `.innerHTML` DOM writes with secure browser `DOMParser` APIs for SVG parsing.
- Configured `esbuild` and `package.json` to recursively copy `tikzjax-assets/` to both development and production release locations.
- Removed temporary extraction scripts to keep runtime codebase clean.
- Added asset origin citations to module README, project root README, and MkDocs features documentation.
- Fixed all 111 ESLint type check and style errors, ensuring clean linter execution.
- Deleted unused CSS/SCSS files: generated-styles.css, obsidian-styles.css, styles.scss, framed.scss, plain.scss, mathwiki.scss, vivid.scss, and main.css.
- Introduced new `main.css` with optimized styles for equation numbering, theorem callouts, and dependency validation.
- Updated esbuild.config.mjs to copy `main.css` to the development vault.
- Simplified `renderSuggestion` in `core-search.ts` and removed redundant class logic in `modal.ts`.
- Streamlined styling and improved maintainability while enhancing search behavior.
