Code should be readable and consistent: avoid inline “magic” expressions, prefer named values/helpers, and use uniform style primitives.

Apply:

• Replace inline calculations with a named variable/helper when the expression is meaningful or potentially repeated:

  const lastEdgeIndex = yy.getEdges().length - 1;
  $$ = $LINKSTYLE;
  yy.updateLink([lastEdgeIndex], $stylesOpt);
  

• Prefer consistent layout/style primitives over ad-hoc spacing classes (e.g., use flex gap-* instead of mixing mr-*, mb-*):

  <li v-for="{ iconUrl, featureName } in column" :key="featureName" class="flex gap-2 items-center">
    <img :src="iconUrl" :alt="featureName" class="inline-block h-5 w-5" />
    <span></span>
  </li>
  

• Keep syntax and typing consistent (e.g., avoid unnecessary token quoting in grammars; align TS/ref typings across related structures).
• In scripts, use safe quoting/argument handling consistently (prefer arrays + "${args[@]}" for pass-through arguments).
• Remove unused grammar/lexer states or keep only what’s actively used; maintain logical rule ordering where it improves scanability.
