  "**Two to an orbital.** Each holds two electrons of opposite spin and never a third; every count follows from that.",
  "**The order, then the facts.** The usual filling order is used, and the eight measured exceptions up to xenon override it.",
  "**Unpaired counted.** Electrons spread across a subshell's orbitals before they pair; the card counts the unpaired ones.",
  "**Stops at xenon.** Past 54 the exceptions multiply; the card refuses rather than guess, and points to measured tables.",
  "**Short form and long.** Each arrangement is given after its noble-gas core and in full.",
  "**Plain words.** why explains what the rule does for matter without equations."
