/* Report Studio: shared styles.
 *
 * CSP-strict: every style lives in a stylesheet (no style="" attributes, no <style> blocks).
 * Naming is BEM-like: .block, .block__element, .block--modifier; state classes use is-*.
 *
 * Responsive, mobile-first. Breakpoints (min-width): 640px tablet / narrow window, 1024px laptop,
 * 1440px wide. The page itself never scrolls sideways: anything intrinsically wide (a table)
 * scrolls inside its own .table-frame.
