/**
 * Single CSS string for chip-density action buttons (Recent / Search /
 * Find / Display, plus the inline Display popover's submit / cancel
 * buttons).
 *
 * Shared between the empty-state chip's action row and the
 * `<DisplayChipAction>` popover so both render with byte-equivalent
 * styling — no per-call ad-hoc Tailwind chain that drifts over time.
 *
 * Sizing intent: 11px font + tight `px-2 py-1` padding lands below UI-Kit
 * `Button size="small"` (24-32px min-height). These are chip-density
 * action buttons, not standard buttons — they sit inside the empty-state
 * chip card's tertiary action row.
