/* tradox's own palette.
 *
 * Dark-first, and not as a style preference: this is a screen people keep open
 * while markets are moving, and a page that glares at 3am gets closed.
 *
 * The accent is one colour and it means one thing - "a measurement stands
 * behind this". It is never used for decoration, so when it appears it carries
 * information rather than mood. `--up` was moved to a lime-green in the 2026-09
 * redesign because the old up-green sat beside the teal and a measured number
 * read as a price rise.
 *
 * The old names (--ink-dim, --ink-faint, --accent-dim, --bg-raised) are kept
 * as var() aliases of the new ones, so the pre-redesign stylesheets reskin
 * without edits and can never drift from the token they stand for; new code
 * uses the new names. The three card elevations are --bg-card, --bg-hover
 * (raised) and --bg-pop; --bg-raised is the legacy alias of --bg-card. */
