/*
 * Signature pad (D-08, D-15, M-03): neutral-100 field, 2px dashed neutral-400 border, radius 22px,
 * 190px tall (180px inline on training, fills the screen on phones). Clear top-right, prompt
 * centered, a baseline with an "×" mark. The canvas fills the field; touch-action none so drawing
 * never scrolls the page. Driven by the signature-pad Stimulus controller.
