/* Running-cost worksheet styles (specs/003-guide-audit-fixes FR-030).
   Moved out of RunningCostWorksheet.astro's scoped <style> so the rules ship
   only on pages that render the worksheet: the component links this file with
   styleSrc(). Astro scoping no longer applies, so every selector is namespaced
   under .running-cost-worksheet to keep the generic class names (.form-group,
   .result-card, ...) from leaking onto the rest of the page. */
