Refines the official site's visual identity with muted blue accents, simpler navigation, and a solid primary action. The SQL ribbon is level and contained, with vertical separators instead of dots.

The sculpture now sits in a physically lit studio with a matte floor, curved backdrop, and cast shadow. Orbital tracks, orbiting dots, and star particles are removed. Softbox lighting and a lighter brushed-metal finish make the database surface more legible while retaining the polished lid's jewel reflection. The static preview and all 64 low-power fallback views are regenerated from the same scene; square fallback frames retain the complete floor instead of clipping it.

The landing page uses the existing Tabler theme properties directly, along with the existing syntax colors. The parallel --brand-* palette and landing color/font aliases are removed. Translucent finishes derive from the shared theme with color-mix(). Native Tabler utility colors retain their default values so component foregrounds, including white toast notifications, remain correct; landing backgrounds use the existing surface properties.

Fixes the streaming comparison's invisible progression: stage fills had collapsed to the panel color. Distinct stage colors and rails restore the animation without changing its timing or pause, tab, and reduced-motion controls. Adds a regression assertion for visible fill contrast.

Comparison-carousel navigation tracks its requested destination during smooth scrolling, so consecutive clicks advance reliably. A rapid-click regression check covers the race, and native scrolling and resizing reset the destination.

CI Hurl jobs retain ubuntu-latest and install Ubuntu's native Hurl package with its matching runtime dependencies.

Validation:

• npm test: 85 tests passed; formatting/lint and type checks completed (existing lint warnings remain).
• npm run build: passed.
• Complete Playwright suite using system Chromium and a rebuilt local executable: all 145 tests passed, including documentation, fixtures, the toast regression, and rapid carousel navigation.
• Inspected live studio artwork and the streaming panel; regenerated the static preview and 64 fallback views.
• Existing multi-step forms Hurl suite passed in an Ubuntu 26.04 container using the exact CI options.
• GitHub CI run #3463: all checks passed on ade8d051, including Playwright and the Hurl examples.
