Most mornings move through a Spelling Bee style word hunt, a quick crossword, a few anagram rounds, and a Scrabble like rack in her head, words turning over while the coffee is still hot.

Readers come for wins that feel earned: familiar vocabulary, steady difficulty, and none of the gotcha tricks that make a puzzle feel smug.
