/* Semester Companion. Hebrew, RTL, phone first. Logical properties only, so the layout mirrors by itself.
   Material: one fixed "sky" of soft light, tinted by the courses with the largest gap, and glass panels over it.
   Only panels blur. Anything inside a panel is a flat tint, because glass on glass loses legibility. */
