/* Stafett control plane.
 *
 * Design tokens and hairline-grid conventions come from the approved
 * dashboard direction: zero border-radius, no shadows, --ink for structural
 * borders and --line for internal dividers.
 *
 * Inter is loaded as a webfont in base.html because the design leans on its 850
 * display weight and nothing here synthesises it (ADR 0023). The stack keeps a
 * locally installed Inter ahead of the webfont and system-ui behind it, so the
 * dashboard still renders if the font origin is blocked or offline.
 *
 * Mono stays on the platform stack: the mock used JetBrains Mono for
 * prototyping only, and the handoff asks production not to add a second face.
