/* studio.css — the quantitative-visual workspace.
 *
 * One precision-workbench language: complete light/dark semantic tokens,
 * hairlines and spacing instead of gradients or glass. Four intents live
 * in the top bar; Create is one Workspace bench (Data · Explore · Canvas);
 * the brief floats or docks. Every control is one --ctl-h row high so
 * toolbars align. Semantic colors (good / warn / critical) stay separate
 * from the accent. Charts inherit the tc- tokens, re-pointed at the
 * studio palette here. */
