Snippet Name: Selection Toolbar
Description: A floating neo-brutalist toolbar that appears over selected text offering highlight, copy, and share actions.
Author: DevSnips Contributors
Usage Example: Wrap any article with the data-selection-toolbar scope; selecting prose opens the toolbar. Highlight wraps the range in a <mark>.

      <p>
        Every product team has a version of the same meeting. The feature works, the tests pass,
        and someone on the call says the interface still <em>feels off</em> in a way no ticket can
        quite capture. The room treats that feeling as a luxury, and the polish it asks for goes
        to the bottom of the backlog. That is a mistake — and it compounds.
      </p>
      <p class="mt-4">
        Rough edges accumulate the way interest does. A focus ring that never shows, a tooltip that
        flickers, a button that does not visibly respond to press — none of these block a task on
        their own, yet together they teach people to trust the product a little less with every
        interaction. <mark class="bg-[#FFE600] px-0.5 font-medium text-black">Rough edges compound.</mark>
        Users may never quote the defect, but they will feel the average of every one of them.
      </p>
      <p class="mt-4">
        The fix is not heroics on a launch week. It is a standing budget for the last 1%: motion
        tuned to 150ms ease-out, selection states that announce themselves, empty states written
        like a colleague instead of a linter. Pick the details most worth sweating and make them
        part of done.
      </p>
      <blockquote class="mt-6 border-l-4 border-black bg-neutral-50 px-4 py-3 font-medium text-black">
        Users never separate polish from quality. To them, one is simply evidence of the other.
      </blockquote>
      <p class="mt-4">
        Polish is not the coat of paint applied after engineering. It is the difference between a
        tool that is merely correct and one that is a pleasure to operate — and it is why the
        interface, not the feature list, is where brand gets built. Sweat it deliberately, or
        watch it leak.
