What this fixture exercises
Joy is the curriculum.
Every surface is built for the next correct answer — green to celebrate, chunky shadows to invite the press, and Duo waiting on the other side.
Tactile 4px shadow
--elev-raised drops a hard 4px offset under every button. On :active we translateY(4px) and zero the shadow — the button literally presses.
Read the rule →Big confident type
--text-4xl (56px) is +25% over typical product brands. Feather Bold at 800 is the default — we never whisper, we never apologize for size.
