a19e0f205fNiveus read flat: thin sheens, short shadows, opaque grey chrome and a painted canvas. This retunes values and component internals only; every class and token name is unchanged, so existing pages pick it up as is. - Canvas: a faint accent light falls across the page, so translucent layers have something to show through. - Surfaces: the surface sheen runs the full height (lit top, shaded foot); raised and filled sheens, highlights and bevels are stronger; the elevation scale is deeper and softer. - Translucency: cards, dialogs, the sidebar and tab tracks let some of the canvas through, with blur so busy grounds never read as texture; frosted and glass materials are clearer with more blur. - Filled buttons give off a soft glow of their own color. - Light fields are paper instead of grey wells that looked disabled. - Fixes: navigation bars wrap and lists scroll inside them instead of overflowing the page on phones; choice labels sit at control size; disabled ghost buttons no longer grow a filled well; the color-swatch rule is split so neither engine drops it.

Niveus — Dialog
|
|
--------------------------------------------------------------------------
|
|
Built on the native <dialog> element, so focus trapping, the top layer,
|
|
Escape-to-close and inertness come from the platform rather than from
|
|
script.
|
|
|
|
<dialog class="nv-dialog"> … </dialog> opened with .showModal()
|
|
.nv-dialog--sheet enters from the block end
|
|
.nv-dialog--wide | --compact width
|
|
.nv-dialog__header / __body / __footer / __close
|
|
|
|
The dialog is the system's highest material: elevation 4 over a blurred
|
|
scrim. It enters by rising and settling, and leaves the way it came — the
|
|
motion is what tells the user the surface was always there, above the page.
