/*
 * Improvements view stylesheet (.imp-* — admin-only self-improvement loop).
 *
 * Spec: continuation of the per-view CSS-extraction discipline.
 * Extracted from inline <style> at pwa/views/improvements.js (the original
 * block that lived just below the `container.innerHTML = ...` initializer
 * before the parallel-session extraction). All hex/rgba literals tokenized
 * via color-mix(...) on var(--color-*) so dark/light themes both work.
 *
 * Repaired 2026-05-03: a botched extraction commit dumped JS code (loadData,
 * clearRestartCountdown, partial postRestart) into this file. Those have
 * been restored to improvements.js; this file is now CSS-only.
