Version 0.5.0 - SuperCards

New Features

Author and study code directly on your cards, with first-class rendering on both desktop and mobile:

Code Block Element: A new Card Editor element for multi-line code, with language selection and syntax highlighting for over a dozen popular languages
Preview Pipeline Support: The preview generation pipeline was extended so code blocks render into card preview thumbnails exactly as they appear in the editor
Mobile Study Mode Rendering: A new CodeBlockView on iOS renders the same code blocks using HighlightSwift, keeping the study experience visually consistent across platforms

Write real math on your cards and have it rendered crisply everywhere you study:

Block Math Authoring: A new block math element in the Card Editor accepts LaTeX/TeX input and renders it as an SVG inside the card
Shared Single Renderer: The app now uses mathjax-full as the single TeX-to-SVG renderer driving the editor preview, card preview thumbnails, and iOS Study Mode — so you see the same bytes everywhere, no platform drift
Mobile BlockMathView: iOS Study Mode now renders block math fragments through a dedicated BlockMathView, with TextElementView handling inline math fragments alongside regular rich text

Highlight Mark in the Editor: A new highlight mark is available across the Card Editor, sitting alongside bold, italic, color, and the other text formatting options
End-to-End Rendering: The ProseMirror parser — on both desktop and iOS — now understands the highlight mark, so highlighted text round-trips from authoring to Mobile Study Mode without losing formatting

Responsive Toolbar: A new toolbar item registry plus a responsive layout hook let the EditorToolbar adapt cleanly to available width instead of clipping or wrapping unpredictably
Refreshed Iconography: Updated and replaced a set of EditorToolbar icons, with color and spacing polish across EditorToolbar and EditorPanel for a more consistent feel

Rich Text Fragments: ProseMirrorParser now returns a structured RenderFragment array, and TextElementView renders from those fragments — a cleaner foundation that made code blocks, block math, and highlighting possible on iOS
Header Consistency: LibraryView and ProfileView headers were refactored for a more consistent look and layout

Save Button Accuracy: Save logic and empty-card preview handling were tightened, and dirty-card tracking now stays accurate across all in-editor and cross-window operations — so the EditorPanel Save button only fires when there are actually cards with unsaved changes
No More Phantom Unsaved Cards: A new updateElementGeometry action prevents layout auto-corrections from marking cards dirty when the user hasn’t actually touched them
Cross-Window “Edit Card” to Same Deck: When the editor receives an editor-init event for a card in the currently active deck, it now navigates directly to that card by id — preserving dirty-card state across the switch with no modal interruption
Minimized Editor No Longer Blocks: Opening a card into an existing, minimized editor window now unminimizes, shows, and focuses the window on the main thread before emitting editor-init, fixing an issue where UnsavedChangesModal would silently block the user from loading a different card

Settings Page Update Button: pendingUpdate was promoted from a useRef to module scope so the “Install & Restart” button on the Settings page can actually use it, letting users install and restart from Settings when an update is detected (previously only the S menu entry could)

Added mathjax-full as a shared TeX→SVG rendering dependency; PACKAGE_VERSION in vite.config.ts is hand-kept in sync with the installed version
Card Editor toolbar architecture moved to an item-registry + responsive-layout hook pattern, making it easier to add or reorder toolbar items going forward
iOS rich text rendering migrated to a RenderFragment-based pipeline, unlocking code blocks, block math, and highlight marks on Mobile Study Mode
