Learn how Grafana list variables let you add dynamic filters to dashboards without editing queries. Build chained, hierarchical filters, avoid duplicates, and manage refresh modes for optimal performance.
Learn how to use Packer's HCL2 variables and locals to share common settings across multiple builders, keep templates DRY, and switch between environments with a single file.
Learn how to define, scope, and safely modify Less variables for consistent theming, source‑map debugging, and runtime theme switches while understanding trust boundaries and failure modes.
Decide whether to use Figma Variables or Styles for your design tokens. Compare token types, theming, and developer handoff in a clear table, then walk through a concrete export example and validation checklist.
Learn how to define, scope, and safely use CSS custom properties with fallback values, plus common mistakes to avoid.
Use Packer 1.6+ HCL2 to parameterize builders, provisioners, and post‑processors. This guide shows the minimal design, trust boundaries, and operational checks for a reusable, version‑controlled image build workflow.
