/*
 * Trade Desk.
 *
 * ONE RULE ABOVE ALL: no physical edges. No `left`, no `right`, no
 * `margin-left`, no `padding-right`, no `text-align: left`. Use the logical
 * properties — inline-start / inline-end, margin-inline, padding-inline,
 * border-inline-start, text-align: start / end, inset-inline. They flip with
 * the document direction; the physical ones do not, and this app is
 * English-first rather than English-only. CssLogicalPropertiesTest greps this
 * file and fails the build.
 *
 * The palette is dark and committed: no light variant. These are numeric,
 * dense screens that people leave open for hours, and a half-considered second
 * theme reads worse than one theme done properly. Every colour is painted
 * explicitly for the same reason.
 *
 * Semantic colour is separate from the accent. Teal is "actionable"; green and
 * red mean long and short, or safe and dangerous, and are never spent on a
 * button just because it needs colour.
