 * Button reset is ID-scoped so it cannot restyle MiP masthead/nav.
 * Do not let this reset paint background/color/padding — w4-web failed
 * because `#dxfdr-app button { background: none }` (1,0,1) outranked
 * `.convert-segment button.is-selected` (0,2,1) and `.btn-export-dxf` (0,1,0).
 * SolidOut's reset is unqualified `button { background: none }` (0,0,1)
 * and loses to those class rules.
 *
 * Specificity fix: keep the ID reset for font/cursor/native chrome only,
 * and ID-qualify every rule that must paint. Then:
 *   `#dxfdr-app .convert-segment button.is-selected` (1,2,1)
 *   `#dxfdr-app .btn-export-dxf`                     (1,1,0)
 * both beat `#dxfdr-app button` (1,0,1) even if background:none is re-added.
