@context
  > The calculator is interactive and stateful via URL query params. Defaults are stripped (so a default-state URL is just /calc). GPU short aliases supported: 4090, 3090, 5090, m5-max, m3-ultra, h100, etc. Context accepts short forms like 8k, 32k, 128k. Tab values: curated | search | size. The "↗ copy link" button in the calculator header copies the current URL to clipboard.
