Control And Visual Fidelity Contract

Use rest, hover, focus-visible, pressed, activated, current, and disabled. Implement the recorded delta on the element that owns it: target, ::before, ::after, or nested icon. Source-observed states outrank normalization defaults. If source focus evidence is absent, add a perceivable :focus-visible treatment without replacing source hover or current styling.

Text geometry

Important text records include inlineSize, blockSize, lineCount, wrapPolicy, maxWidth, fontSize, and lineHeight. At the canonical desktop viewport, a captured single-line heading is an identity lock. Match its container width before shrinking type.

Stateful collections

Respect initialState and initialActiveIndexes. all-collapsed means no item may be opened during runtime initialization. Reproduce separation.mechanism: it distinguishes track gaps, geometric gaps, margins, dividers, inner insets, and flush items.

Motion ownership

data-rp-visual marks the measured visual transform owner. data-rp-content marks copy whose geometry is verified separately. Never nest static content inside a scaling visual wrapper unless source evidence explicitly says the content scales.

Logos and icons

Logo priority is exact source file or materialized source SVG. Preserve all observed variants and usage sizes. Never recreate a logo as text or substitute a library mark.

Icon priority is exact source asset, then the source sprite/library, then a style-matched established library such as Iconify. Library fallback is only allowed when no source icon exists and never applies to logos.
