Summary
• Extracted `LogoSection`, `NavLinks`, `UserArea`, and `ActionButtons` from `HeaderBar.js`, reducing complexity and improving readability.
• Removed unused state, handlers, and redundant imports from `HeaderBar.js`.
• Simplified mobile/desktop logic:
– Menu icon now shows only on mobile `/console` routes.
– Logo, system name, and mode tags appear on all desktop screens and on mobile non-console pages.
• Reworked skeleton loaders:
– Narrower width on mobile (`40 px`) and clearer spacing (`p-1`).
• Added global `.scrollbar-hide` utility in `index.css` to enable scrollable areas without visible scrollbars.
• Ensured nav bar is horizontally scrollable across all breakpoints.
• Cleaned up language-switch, New Year, and notice handlers; consolidated side effects.
• Updated imports and internal calls after component extraction.
• Passed required props to new sub-components and removed obsolete ones.
• Confirmed zero linter warnings after refactor.
Why
Breaking the monolithic header into focused components makes future updates simpler, facilitates isolation testing, and aligns with the existing component architecture under `components/`. The UI tweaks provide a better mobile experience and consistent styling across devices.
Notes
No backend changes required. All routes and contexts remain untouched.
