/**
 * Select presentation utilities (q-select-* namespace).
 *
 * The TRIGGER reuses the Input field surface (`q-field-control`, see input.css):
 * the bordered white-5% box, lime focus ring, and red `q-field-control-invalid`
 * ring. These rules only add the value/placeholder typography, the flipping
 * chevron, and the sm/lg height presets.
 *
 * The POPUP reuses the Dropdown glass card (`q-dropdown-content`, see
 * dropdown.css) and the shared `q-menu-item*` row primitives (see menu.css), so
 * Select options look identical to Dropdown rows. Only Select-specific chrome —
 * the selected-row glyph alignment, scroll arrows, and group rhythm — lives here.
