Effects

A native range control for comparing two states in the same frame. Both states remain present in the DOM with explicit labels; the clipped surface and hairline follow direct pointer or keyboard input without eased lag. Use it when aligned layers make a visual difference easier to judge.

A relationship figure for a finite set of named items. CurrentColor hairlines sit behind an HTML node list; hover or focus dims only unrelated relationships, and reduced motion shows the complete graph.

A tabbed stack for revisions or document states. Tabs select one semantic panel while two offset paper hairlines preserve the stack metaphor. The active sheet settles once over 300ms; reduced motion presents the selected content at rest.

One isometric scene read from two camera stations. At rest it is a tree standing on a paved plaza; tapped, the camera rises to straight overhead, where the height axis drops out of the projection and the drawing resolves into a scannable code. Nothing is drawn twice — a mark is only ever placed over a module the code already needs dark, and it never leaves that module’s footprint, so the union of the marks seen from above is the matrix. The canopy is carried by hairline outlines and takes its fill only as the code resolves, because only then does the fill carry information. A mark is not a square: paving stays hard-edged so the finder patterns a scanner hunts for stay crisp, wood narrows toward the twigs, and each leaf is a rotated almond that relaxes back into a clean dot as the camera rises. Overhead that leaves the code reading its own footprint — the dotted middle is exactly where the canopy stood. Resting a mouse on the plate previews that reading; the button pins it. The drawing sits on the fixed media ink and paper pair rather than the page palette, because a code that inverts with the theme is unreliable to scan, and the control sits beside the plate rather than over it so nothing can occlude a module.

A branching architecture figure for fan-out, fallback, and fan-in. Permanent currentColor paths and readable HTML labels share the available width without a nested scroller. Phones receive a complete stage ledger and visible route register instead of a miniature or clipped canvas. Selected routes may carry one brief signal on entry; reduced motion keeps only the complete written map.

A user-started scan cue over content that remains fully readable. The currentColor hairline crosses once in at most 380ms, then yields to a written result; hidden tabs finish rather than queueing motion. Reduced motion moves directly from ready to complete.

Ordered architecture stages with nested actors, permanent currentColor arrow lanes, and one semantic list that is also the visual composition. The field keeps fixed-size labels and scrolls on narrow screens. Each connector receives one 360ms signal pass on entry; reduced motion retains the complete diagram without the travelling mark.

A centered currentColor registration frame behind its children. The wrapped content always remains fully present; hover or focus simply lets the decorative hairline recede. There is no global pointer listener, cursor drift, radial mask, or reveal that can lower readable content below the contrast floor.
