Use portable POSIX parent paths instead of platform-dependent dirname() for remote navigation, previews, uploads, file operations and shared URLs.
Normalize browser paths, avoid doubled root separators and preserve top-level directory names in ZIP downloads.
Add regression coverage for root navigation, generated links, relative paths and ZIP members, and document the new test command. Verified with PHP syntax checks and all three regression suites.
Expand README with application features, requirements, XAMPP setup, connection configuration, project structure and troubleshooting.
Add Czech database documentation covering SQL import, manual SQL and phpMyAdmin table setup, bcrypt administrator creation, database permissions and verification.
Provide the missing share table schema as a separate SQL supplement and explain its relationship to the original users dump.
Replace Bootstrap dependencies with custom blue-accented light and dark themes and native dialogs.
Share the sidebar, top bar and responsive layout across file browsing, account settings, user management, server statistics and file previews. Add folder search, type filters, upload progress and asset cache versioning.
Fix SSH configuration usage, filesystem discovery, missing statistics and RAID health parsing. Adapt PDF sizing and fullscreen controls to the shared workspace.
Validation: PHP workspace and server statistics regression tests, JavaScript syntax checks, responsive browser checks and live XAMPP navigation.
