I am also an idiot who needs mnemonics to remember incredibly basic stuff. In a similar vein to OOP, I did a PhD in chemistry with substantial involvement with chiral structures and still don't really know left from right... but I never understood this one. Smaller number on the small side, bigger number on the big side always seemed really intuitive.

Also in a theoretical physics context I think of those symbols as Dirac notation more often than inequalities, but then I'm not a physicist.

Bra-Kets are have much shallower angles and inequalities are still used widely in physics

Fair. There's a reason I barely scraped through introductory quantum.
