WalkthroughAdds CSS rules to fc-enhanced-tabs: defines a focus-ring width variable, computes padding/margin for vaadin-tab inside vaadin-menu-bar-button based on a Lumo flag, and implements focus-visible styling using an inset box-shadow focus ring with resolved border-radius. Changes

- Around line 129-136: The CSS removes the native outline on
vaadin-menu-bar-button[theme~='fc-enhanced-tabs'][focus-ring] and relies on
box-shadow which can disappear in forced-colors/high-contrast mode; restore an
accessible visible focus by adding a forced-colors fallback: wrap a rule in
`@media` (forced-colors: active) targeting
vaadin-menu-bar-button[theme~='fc-enhanced-tabs'][focus-ring],
vaadin-menu-bar-button[theme~='fc-enhanced-tabs']:focus-visible and set an
explicit outline (e.g. outline: 2px solid Highlight or outline: 2px solid
CanvasText) and outline-offset to match the intended ring, or conditionally keep
outline: none only outside forced-colors so the native/high-contrast outline
remains available; update the selectors in the existing block (the
vaadin-menu-bar-button[theme~='fc-enhanced-tabs'] rules and inner
vaadin-menu-bar-item shadow styles) accordingly.
- Around line 109-125: The calc() expressions for padding-block, padding-inline,
margin-block, and margin-inline violate stylelint operator/spacing and have
extraneous blank lines; reformat each declaration so binary operators (+, -, *)
are on the same line as their operands with single spaces around them (or
collapse the entire calc() to a single line) and remove the empty line before
the padding-inline and margin-block declarations so there are no blank lines
between consecutive property declarations; update the padding-block,
padding-inline, margin-block, and margin-inline declarations accordingly to
satisfy stylelint.

calc()blocks to satisfy stylelint.The current line breaks/blank lines in these declarations still match the reported lint violations and may fail CI.
