Migrate to Gradle 8.14 and the GradleUp shadow plugin. Raise the Java toolchain to 17 and resolve the fancy launcher Substance dependency via the CottonMC fork mirror. Fixes SKCraft#546
Per-instance settings now own JVM args, memory limits, and runtime selection so each modpack can be tuned independently.

Download and cache required Java runtimes per instance before launch. Creator tools can pin a managed runtime in the modpack builder. Closes SKCraft#539
…artup Introduce jlink/jpackage-based app images and platform package tasks (Windows NSIS Setup.exe, Linux AppImage/tar/deb, macOS dmg) driven by InstallerPackager, with a root `package` task that delegates to the host OS. Bootstrap now resolves data from the install directory on Windows, migrates legacy Documents data, logs to disk, checks for updates before launch, and drops portable mode in favor of a single configured data directory.
Read newsUrl from each manifest entry so modpacks can override the launcher default news page. Creator tools expose the field in the manifest entry editor.
Skip optional registry lookup instead of logging a warning stack trace when the official launcher is not installed.

Remove the launcher-fancy module and its custom skin/L&F stack in favor of FlatLaf (FlatMacLight/FlatMacDark) integrated into the main launcher. - Add persisted themeMode (light, dark, system) with migration from the legacy darkTheme flag - Expose theme picker in Configuration > Advanced and apply changes live - Restyle dialogs with FlatLaf button classes and drop manual opaqueness hacks - Rework main window layout: MigLayout side-by-side panels instead of JSplitPane, primary launch button, Enter-to-launch on instance list - Sync news WebView with launcher theme via preferred color scheme - Theme-aware link colors and panel borders

Drop JavaFX WebView and embed news via SWT/WebView2 on Windows/Linux and WKWebView on macOS. Browser runtime resolves outside the fat jar via BrowserBootstrap and SwtRuntimeResolver.
Bundle WebView2 on Windows, SWT natives, and per-OS data directories in the bootstrap installer. Add Docker-based Linux packaging from any host, hand off Windows AppUserModelID to the launcher JVM, and extend InstallerPackager for platform-specific naming and runtime assembly.
…lors Stream process output through a ring buffer and batched Document updates. Delay the game log until the client window is ready (or launch fails), optionally maximize on ready, and keep launcher console history in a LogBuffer.
Show pack icons and status text in larger rows, wrap the list and news pane in shared table borders, and clarify instance menu actions.
Support offline play profiles with stable UUIDs, persist the active account, and let users switch or manage accounts from the main frame.
Enforce system RAM limits, verify modpack updates before launch, share HTTP client/download threads, and harden runtime discovery across creator and launcher.

Major launcher refresh on

MigLayout main window, primary launch button, Enter-to-launch. Instance list shows pack icons, status rows, and shared table chrome; remember last launched instance.newsUrloverride in manifests and creator tools; theme sync via preferred color scheme.ProcessorEntryrespects cache before queueing processor tasks; reload instances when game key changes on save.InstallerPackager: Windows NSISSetup.exe(+ WebView2), Linux AppImage/tar/deb (Docker-based Linux packaging from any host), macOS dmg. Bootstrap resolves install-dir data, migrates legacy Documents data, logs to disk, checks updates before launch.Scope: 22 commits, 212 files, ~+15.6k / −2.2k lines.
