  "description": "Variables that are declared with `decrement` are unique to the [layout](/themes/architecture/layouts), [template](/themes/architecture/templates),\nor [section](/themes/architecture/sections) file that they're created in. However, the variable is shared across\n[snippets](/themes/architecture/snippets) included in the file.\n\nSimilarly, variables that are created with `decrement` are independent from those created with [`assign`](/docs/api/liquid/tags/assign)\nand [`capture`](/docs/api/liquid/tags/capture). However, `decrement` and [`increment`](/docs/api/liquid/tags/increment) share\nvariables.",
