+/*
+  RECOMMENDATION:
+     Please do not use the base color variables directly,
+     define a new variable instead that assigns the value of this base variable.
+       Examples:
+         - @base-color: red;
+         - @my-new-var: @base-color;
+         - @my-second-new-var: @base-color;
+
+     Do not use the same variable for different use cases, but define a new variable for each use case.
+
+  NOTICE:
+    Color vars identification:
+      - Vars with `-bg` suffix are background-color vars. Please use only for setting bg-color.
+      - Vars with `-color` suffix are color vars. Please use only for setting fg-color.
+
+  MODE SUPPORT:
+    The standard LESS variables represent the dark mode. The LESS detached ruleset `@iplWebLightRules`
+    contains CSS variables that represent the light mode. It must be used explicitly to have any effect.
+    If you use media queries to support modes, just call the ruleset inside your media query:
+
+      @media (prefers-color-scheme: light) {
+        @iplWebLightRules();
+      }
