+ * Fluid type that increase font size smoothly and linearly between a min and max value
+ * over the viewport width range 360px (XS) to 1500px (2XL)
+ * See concept on https://www.aleksandrhovhannisyan.com/blog/fluid-type-scale-with-css-clamp/
+ *
+ * See google sheet for a plot of the font sizes over the viewport width range 360px (XS) to 1500px (2XL):
+ * https://docs.google.com/spreadsheets/d/1AN9eV_ECXc9MzTZUc10hiLjOHeOCDTutC5tMHOCPqgo/edit?usp=sharing
+ *
+ * Good for use in hero banners and horizontal cards where UI looks better with a smooth transition of font size
+ * Here we offer the sizes from fluid-type-4 to fluid-type-10. Their min and max values at the XS and 2XL breakpoints
+ * are the same as the corresponding modular typography classes (type-4 to type-10).
