Vista Carousel

Features

• One wide two-column glass panel (about 52rem): a translucent smoky fill with a 24px backdrop blur and 140% saturation, a hairline of white at 8% and white ink
• Left column: a vertical tablist of five rows, each a 20px medium-weight title over a two-line description in white at 62%; the active row sits on a single soft white plate (about 9%, menu radius, no border, no accent) that glides between rows, and its title brightens from 80% to full white
• Right column: a rounded preview of the active slide; the incoming photo fades in over 0.7s above the held outgoing one, drifting 2% from the side it travels from, and settles from scale 1.04 to 1 over 1.2s
• The backdrop fills the whole page edge to edge: a still fluted-glass field in golden-hour travel colours: dusk lavender, sunset rose, coral and apricot pools with a sea-teal glow over a dusk-blue base, seen through vertical ribs (a soft-light highlight-to-shadow ramp every 22–40px) under a fine SVG film grain, toned down to 82% saturation and 86% brightness; it never changes with the slide, so only the panel moves
• Stacked below 720px, the panel narrows to at most 34rem and the preview is capped at 40dvh, so the carousel fits a phone-height frame
• WAI-ARIA tabbed carousel: role="tablist" of buttons with roving tabindex, one role="tabpanel" per slide, inactive panels aria-hidden and inert
• ArrowUp / ArrowDown / ArrowLeft / ArrowRight / Home / End move focus with automatic activation and wrap-around; hovering a row with a mouse selects it and clicking selects it
• Autoplay every 5s with a quiet 2px progress line (white at 35%) filling along the active row; hovering the glass panel, focus-within and a hidden tab suspend it and resume the remaining time, while the glass pause control over the preview is a sticky userPaused that survives focus-out
• prefers-reduced-motion: starts paused with the control reading Play, instant swaps, no zoom settle and no progress line
• Own identity in design-systems/vista-carousel/DESIGN.md (smoky glass, white ink, Inter); fonts, radii and spacing follow any other design system, whose primary only reaches the focus ring and the progress line
