One chord a day, drawn by the whole Warrior Network from a single shared seed: a hash of the calendar date over a curated pool, so every sister site is looking at exactly the chord you are. What changes from site to site is the answer, and on a tres the answer is a figure.
A tres does not hold a chord down and strum it. It turns the chord into a guajeo — a short repeating line that walks through the chord tones in rhythm — and hands the sustained harmony to whoever else is in the room. So the useful question about today's chord is not "what is the grip" but "what order do its tones want to come out in".
The page answers it by counting rather than by taste: the root goes to the strong beat, the remaining tones are walked as even eighths across the bar, and the highest sounded course takes the last eighth — the push before the loop returns. Same chord, same figure, every time.
The shape is computed in your browser, from your own calendar date, and never on the server: rendered pages here are cached at the edge for hours at a time, so a date baked into the HTML would cheerfully hand you yesterday's chord a minute after midnight. Once the page knows what day it is where you are, today's chord and its figure appear below.
While you wait — or if scripting is off — the guajeo pages have all three cells recomputed note by note, and the chord reference has the whole library.
