# Gantry Landing Page Run Record - Agent name: Sol - Reasoning level: high - Skill mode: new-skill - Active frontend skill: frontend-art-direction - Exact output directory: `/sol-high/new-skill/01-creative-landing` - Work started: 2026-07-13T14:23:35+08:00 - Work completed: 2026-07-13T14:49:36+08:00 - Elapsed seconds: 1561 - Elapsed HH:MM:SS: 00:26:01 ## Files created - `index.html` — semantic landing-page structure and finished product copy - `styles.css` — responsive industrial editorial design system and reduced-motion rules - `script.js` — navigation, orchestration demo, workflow accordion, and pricing interactions - `RUN.md` — implementation and verification record - `verification-desktop.png` and `verification-desktop-viewport.png` — desktop hero inspection - `verification-control-room.png` and `verification-keyboard-focus.png` — desktop orchestration and focus-state inspection - `verification-features.png`, `verification-workflow.png`, `verification-pricing.png`, and `verification-final-cta.png` — desktop section inspections - `verification-tablet.png` and `verification-tablet-control.png` — tablet hero and orchestration inspections - `verification-mobile.png`, `verification-mobile-menu.png`, `verification-mobile-control.png`, `verification-mobile-pricing.png`, and `verification-mobile-ticket.png` — mobile layout and interaction inspections ## External dependencies None. The page uses only local HTML, CSS, JavaScript, and inline/data-URI SVG. ## Selected design direction “Industrial switchyard”: a warm-paper editorial shell surrounds a dark railway-style agent control board. Signal orange, cyan, and lime encode dispatch, active coordination, and completion. The defining visual is a four-lane route map that converges completed work back into the orchestrator. ## Interactions implemented - Orchestration state tabs: Dispatch, In flight, and Merge ready. Supports click and Left/Right/Home/End keyboard navigation with tab semantics. - Orchestration playback: progresses through the three run states and updates lane status, progress, dependencies, evidence, and merge readiness. Reduced-motion mode skips timed playback and displays the final state immediately. - Workflow accordion: four native-button stages with synchronized `aria-expanded`, regions, and single-panel expansion. - Monthly/annual pricing selector: native buttons with `aria-pressed` state and live price/billing copy updates. - Responsive mobile navigation: native toggle button, Escape-to-close, link-close behavior, accessible name updates, and focus return. ## Verification performed - Opened the exact generated page through a temporary local-only server and confirmed the required document title before inspecting content. - Inspected desktop at 1440 × 900, tablet at 900 × 1000, and mobile at 390 × 844. - Captured and visually inspected hero, control room, capabilities, workflow, pricing, final CTA, mobile menu, and mobile ticket states. - Tested mouse interactions for anchor navigation, orchestration state switching, sequence playback, workflow expansion, pricing toggle, and mobile-menu open/link-close. - Tested custom keyboard behavior for orchestration tabs with ArrowRight, visible focus, mobile Escape-to-close, and focus return. Confirmed all remaining controls are semantic native buttons or links with accessible names and visible `:focus-visible` styling. - Audited logical focus order, selected-tab roving `tabindex`, ARIA state updates, button types, and internal anchor targets. - Checked orchestration playback output, lane progress values, dependencies, completed return packet, and merge-ready state. - Checked reduced-motion CSS and JavaScript branches: animations/transitions collapse and timed playback jumps immediately to Merge ready when the media query matches. - Checked document width and escaping bounds at all three viewports; inspected lane and pricing reflow at tablet/mobile. - Scanned source for external URLs, network assets, unfinished copy markers, title metadata, and relative local asset references. - Ran `node --check script.js`. - Checked browser console warnings/errors and runtime asset URLs. - Listed the final output directory after verification to confirm every generated file is contained there. ## Verification results - PASS — required title and benchmark metadata comment are exact. - PASS — required navigation, hero, two CTAs, orchestration demonstration, feature overview, workflow, pricing preview, final CTA, and footer are present with finished copy. - PASS — orchestration communicates four specialized agents, current status, progress, dependency edges, and completed output returning to the orchestrator. - PASS — all implemented interactions produce the expected visible and ARIA states. - PASS — custom tab keyboard navigation moved from In flight to Merge ready and retained a visible focus outline. - PASS — mobile navigation updates its accessible name, locks the page while open, closes on Escape or destination click, and returns focus to the menu toggle. - PASS — no horizontal overflow at 1440, 900, or 390 px after clipping the decorative hero route mark to its section. - PASS — no missing anchor targets, no buttons without `type`, no network-loaded assets, and no browser console errors or warnings. - PASS — JavaScript syntax check completed with exit code 0. - PASS — `styles.css` and `script.js` use relative paths and every dependency is local, so opening `index.html` directly does not require a server or network. - PASS — all 18 generated files are inside the exact assigned output directory. ## Known limitations - Beta CTAs intentionally use `mailto:` because this is a standalone, backend-free landing page. - System-resident fonts are used so rendering remains fully offline; exact font availability varies slightly by operating system. - The controlled browser blocks `file://` navigation by policy, so direct-file opening was verified from the relative asset graph and dependency scan; browser visual acceptance used the identical files through a temporary localhost server. - No subagent launcher was exposed in this session. The required acceptance review was performed as a fresh, read-only audit pass by the root agent before final verification.
