Memos
A memo is not a reference. A reference is complete and you read into it; a memo carries one technique and is meant to be absorbed and then ignored. That difference decides the whole layout — fewer items, larger, with the thing you actually do made the biggest object on the page.
The memos here are the first chords on guitar and ukulele, coffee ratios by brewing method, the matcha drinks, converting imperial units in your head, the flexbox properties, and where a change is sitting in Git.
They are for the wall directly in front of you — beside the instrument, over the kettle, next to the screen. Not for a shelf.
