+ * Global LESS variables. An associative array binding variable names to
+ * LESS code snippets representing their values.
*
- * Because the hashed contents of this array are used to construct the cache key
- * that ResourceLoader uses to look up LESS compilation results, updating this
- * array can be used to deliberately invalidate the set of cached results.
+ * Adding an item here is equivalent to writing `@variable: value;`
+ * at the beginning of all your .less files, with all the consequences.
+ * In particular, string values must be escaped and quoted.
+ *
+ * Changes to LESS variables do not trigger cache invalidation.
*
* @par Example:
* @code
* Custom LESS functions. An associative array mapping function name to PHP
* callable.
*
- * Changes to LESS functions do not trigger cache invalidation. If you update
- * the behavior of a LESS function and need to invalidate stale compilation
- * results, you can touch one of values in $wgResourceLoaderLESSVars, as
- * documented above.
