packages/core/src/theme/components/PackageManagerTabs/index.tsx:66

• transformDenoPositional only treats --... tokens as flags. With the new default deno run -A, -A is a short flag that does not start with -- and will be treated as a positional argument and incorrectly rewritten to npm:-A (and then the actual script/tool may stop being transformed). Update the positional detection to also exclude short flags (tokens starting with -), and (if applicable) exclude their flag-values similar to the existing --... logic.

  const subcommand = parts[1];
  const isRun = subcommand === 'run';
  let transformedFirst = false;

  const transformed = parts.map((tok, idx) => {
    // only transform positional args (after "deno" and the subcommand)
    if (
      idx >= 2 &&
      !tok.startsWith('-') &&
      !tok.includes(':') &&
      !/^https?:/.test(tok)
    ) {
      if (isRun && transformedFirst) {
        return tok;
      }
      transformedFirst = true;
      return `npm:${tok}`;
    }
    return tok;
  });

• The fixture doc now renders an additional <PackageManagerTabs ... /> (multi-arg dlx) while still keeping the original dlx and exec examples, so the page likely has 3 tab groups (15 tabs), not 2 (10 tabs). Either update this expectation to match the new number of rendered tab groups, or change the test query to scope to the specific PackageManagerTabs instance(s) it intends to assert.
