1---2name: mengto-split-layout-technical3description: Use when designing a technical split-screen system with dual panels, fine frame lines, mono metadata, quiet editorial typography, and premium inset surfaces. Prefer this over mengto-bright-green-tech-system-webgl when dual-panel split framing leads without a bright-green WebGL viz mandate.4---56# Split Layout Technical Skill78## Use When9- Create a technical split-screen design system with dual panels, fine frame lines, mono metadata, quiet editorial typography, and premium inset surfaces.1011## Workflow1213## Scope14- Apply this as a full-page layout and design-system direction when the interface should be organized into two clear panels or halves.15- Use it for product pages, showcases, portfolios, editorial-tech layouts, or concept presentations that benefit from a disciplined split-screen structure.16- This is a layout system first: it should control framing, spacing, typography, metadata treatment, and panel behavior, not just add a vertical divider.1718## Visual target19- Build the page around a strong split layout, usually two equal or near-equal vertical panels on desktop, with each side carrying a distinct role.20- One side should act as the hero or immersive focal panel, while the other side handles explanation, specs, metadata, supporting content, or navigation.21- Use thin frame lines, inset boundary rules, tiny corner markers, and precise spacing so each panel feels like a technical display surface.22- Pair quiet editorial typography with mono utility labeling so the system feels intelligent, architectural, and controlled.23- Keep the palette restrained, with neutral surfaces and one selective accent color derived from the design rather than a hardcoded hue.2425## Implementation guidance26- Prefer `flex-row`, split columns, or a clear two-panel grid on desktop, then stack the panels vertically on smaller screens without losing the sense of separate zones.27- Give each panel its own internal framing: inset vertical rules, edge offsets, corner squares, thin borders, or measured padding that creates a contained shell.28- Use mono or utility text for top rails, metadata strips, labels, coordinates, system markers, specs, or status copy.29- Main headlines should remain clean and confident rather than loud; support them with controlled tracking, restrained hierarchy, and generous spacing.30- Feature one premium embedded surface inside at least one panel, such as a bordered media frame, canvas region, visualization area, or image window.31- Let one panel feel denser and more informational while the other feels more visual, spatial, or atmospheric to create useful contrast.3233## Recommended patterns34- Left/right split hero: immersive artwork or media on one side, explanatory content and structured details on the other.35- Technical rails: slim top labels, footer metadata, coordinates, version markers, timestamps, or publisher-style microcopy in mono.36- Specification blocks: compact two-column facts, thin dividers, line-separated rows, and restrained tabular presentation.37- Framed surfaces: gradient-border wrappers, inset shadows, clipped media windows, or dark technical canvases placed inside a quiet outer shell.38- Panel asymmetry: keep the overall split balanced, but allow different content densities and vertical rhythms inside each half.3940## Tuning knobs41- Split ratio: use 50/50 by default, but shift slightly when one side needs more dominance.42- Frame density: increase or reduce the number of inset rules, corner markers, and dividers depending on how technical the system should feel.43- Typography mood: steer more editorial with larger serif-like display moments, or more product-technical with cleaner sans and mono emphasis.44- Surface depth: tune border gradients, inset shadow strength, and internal panel contrast so embedded surfaces feel premium but not heavy.45- Accent restraint: use the accent for active details, system cues, or focal content, not as a blanket color wash.4647## Avoid48- Generic two-column marketing layouts that lack structural framing and technical detail.49- Overcrowding both panels equally so the split loses hierarchy and purpose.50- Bright multi-color treatments that break the calm, technical tone.51- Rounded playful UI patterns that fight the precise architectural layout.52- Treating the split only as decoration instead of giving each half a distinct functional role.
