/* Update the app UI to match a professional MCDA decision-support dashboard style.

Design direction:
Create a clean, institutional research-software interface. The app should feel polished, calm, and functional, not like a marketing landing page. Use a white page background, restrained blue primary color, clear spacing, subtle borders, and compact information-dense layouts.

Visual style:
- Main background: white.
- Primary color: #325D88.
- Primary dark: #244767.
- Primary soft background: #e7eef5.
- Accent color: #b76b43, used sparingly for small emphasis only.
- Text color: #1f2933.
- Muted text: #5f6f7a.
- Borders: #d7e0e6.
- Border radius: 6-8px.
- Shadows should be subtle, e.g. 0 2px 8px rgba(31, 41, 51, 0.07).
- Avoid decorative gradients, oversized cards, and one-page marketing styling.

Layout:
- Use a centered page width around 1120px.
- Page padding should be about 32-36px top and 24-28px bottom.
- Use consistent page titles across pages with the same class/style.
- Titles should be left-aligned, dark blue, bold, and around 2rem.
- Section headings should be smaller, dark blue, and left-aligned.
- Keep tool pages compact and workflow-oriented.

Navbar:
- Use #325D88 as the navbar background.
- Text should be white or near-white.
- Active/hover nav links should use a subtle translucent white background.
- Do not put a white box/background behind the logo.

Footer:
- Use a very light gray footer background, e.g. #f8fafc.
- Add a subtle top border.
- Footer text should be small, muted, and readable.

Buttons:
- Primary actions use #325D88 with white text.
- Secondary actions use outline buttons with the same palette.
- Download/export buttons should use the same secondary outline style, not unrelated light-gray buttons.
- Keep buttons rectangular with small radius, not pill-shaped.

Forms and inputs:
- Inputs, dropdowns, accordions, sliders, and tables should use the same blue focus color.
- Focus rings should be subtle, e.g. rgba(50, 93, 136, 0.16).
- Dash sliders should use #325D88 instead of default purple.
- Dropdown selected/focused states should use a soft blue background.

Upload boxes:
- Main upload controls should remain full drag-and-drop boxes.
- Use dashed border, white background, subtle shadow, 8px radius.
- Upload text should be concise: “Drag and Drop or Select Files”.
- Hover state should change border/background softly using the primary blue palette.

Tables:
- Tables should have subtle borders and light header backgrounds.
- Empty helper/placeholder tables should not create visible blank boxes.
- Use compact cell padding and clear headers.
- Comparison/recorded-results tables should be easy to scan.

Recorded results / comparison UI:
- If users can record multiple runs, show a “Recorded methods” list above the comparison table.
- Repeated method runs should be labeled with counters, e.g. ARAS 1, ARAS 2, Meta-MCDA 1.
- Each recorded run should have an individual Delete button.
- Also provide a Clear all recorded methods action.

Progress feedback:
- Long-running simulations should show a progress bar.
- Progress polling should be disabled by default and only enabled while the simulation is running.
- Show current round and total, e.g. “37 / 500”.
- Stop polling when complete or on error.

Home/reference content:
- Long method lists should not be shown as individual cards.
- Use compact multi-column text lists for many methods.
- Use cards only when they frame actual repeated items or tool surfaces.

Overall:
Make the UI consistent across Home, Meta-MCDA, Calculator, and Robustness pages. The result should look like one coherent professional research tool. */
