01 / Why it exists
Make a closer look easier
Invoke treats each screen pattern like a small command: select it, enter a focused view, make an observation, and return to the deck.
The interface supports keyboard, pointer, and touch input. Its output is visual context—not a benchmark, repair utility, or diagnostic report.
02 / What you can inspect
Nine focused visual references
Solid ColorCycle through black, white, RGB, cyan, magenta, and yellow to look for unusual bright, dark, or fixed pixels.
Black ScreenUse an uninterrupted black field to inspect possible edge glow, bleed, clouding, or uneven dark areas.
Uniformity FieldsCompare center, edges, and corners across neutral fields at several brightness levels.
Pixel GridSwitch among horizontal lines, vertical lines, a reference grid, and a checker pattern.
Sharpness TargetInspect fine text, radial lines, concentric targets, and corner detail for apparent softness or halos.
Contrast StepsCompare near-black and near-white steps to see whether adjacent tones remain distinguishable.
Grayscale RampView stepped and continuous gray ramps for abrupt jumps, tinting, clipping, or visible banding.
Color RampsInspect red, green, blue, cyan, magenta, and yellow transitions from dark to bright.
Motion TrailTrack a moving reference at three speeds to compare perceived blur, trailing, and animation smoothness.
03 / Principles
How Invoke is designed
Fast launch
Core tools are immediately available from the first viewport.
Keyboard-aware
Common transitions have straightforward key controls.
Local execution
Patterns run in the browser without uploading results.
