Built-in imagegen; ui-mockup; concept only. Generated 15 September 2026. Source: exec-626efda8-cac8-4f93-a497-691969ec7361.png. Use case: ui-mockup. Create a restrained high-fidelity native macOS product design exploration board for Workbench, an open-source presentation utility. This is a DESIGN CONCEPT, not shipping UI. Show 3 well-composed views of the same real workflow on a clean warm-white board, landscape. Typography crisp Apple-style sans-serif, muted slate and warm-white, quiet teal accents, native popovers, comfortable click targets. Large main view: a fictional browser business app called Service desk with two transparent floating audience overlays simultaneously: bottom right a modest illustrated woman persona badge labelled 'Site manager', top left a small clean caption card reading 'Report an issue'. No celebrity, real customer or real company logos. Tiny native dark control tile at bottom centre: stacked-rectangles icon, '2', separator, chevron. No Live label, no Demo label, no persistent progress lights. Second view: same tile CLICK expanded into a concise popover showing 'Set 1 of 2', previous/next buttons, two visible-item rows 'Site manager' and 'Report an issue' with visibility toggles, 'Hide all', 'Arrange', and 'End overlays' clearly separated. Third view: preparation in a real Mac window titled 'Personas', a short private Groups sidebar 'Service walkthrough', 'Manager view', and a restrained placement preview with same 2 cards. Caption headings exact: 'Prepare', 'Present', 'Pause and return'. Small footer exact: 'Design exploration — click to open, keyboard accessible'. Explore clarity and white space, no oversized marketing headings, no chart dashboard, no glowing neon or fake AI sparkles. Depict manual set changes across tabs/apps; no automatic attachment or private invisible HUD claims. Animation shown only by a very small annotation 'Optional soft reveal' beside an overlay, no blinking faces, no animated avatar effect. Selected implementation differs: a native click menu supplies live controls. The preparation window uses Workbench's existing persona library, not the speculative sidebar drawn here. No claim of automatic browser-tab attachment, hidden meeting controls or a new caption generator follows from this concept.
