/*
 * Form controls. design/DESIGN-SYSTEM.md §4.13, grid from §3.4.
 *
 * Field chrome is quoted exactly: #111 ground, 1px rgba(255,255,255,0.16)
 * border, 14px padding, 15px text, radius 0. The focus state is the replacement
 * §4.13 asks for (the prototype sets `outline:none` and stops); it already lives
 * in base.css, so nothing is repeated here.
 *
 * The prototype has no error state -- it has no server. Errors therefore reuse
 * the design's single accent: the field border turns red and the message is set
 * in the helper-text size, so nothing new enters the palette.
