/* styles.css — Project Control Dashboard (pcpm)
 * Light theme with an automatic dark-mode override (prefers-color-scheme).
 * Colours come from CSS variables so re-theming is a one-place change.
 *
 * v2 layout pass: darker page canvas + stronger panel shadow + accent tick on
 * section headers, so each area (Gantt, Milestones, Actions, RAID) reads as a
 * separate block instead of blending into one white sheet. */
