/* ============================================================================
 * fleet.css — Vivetra Fleet Ops — the one stylesheet
 * Version: 1.1
 * Last Updated: 2026-07-20
 *
 * PROJECT: Vivetra (project v0.53) — vivetra-fleet component (central ops box)
 * FILES:   sites/vivetra-fleet/css/fleet.css   (this file)
 *          sites/vivetra-fleet/inc/layout.php  (links it, emits the markup)
 *          sites/vivetra-fleet/pages/*.php     (the screens it styles)
 *
 * FILE CONTEXT:
 *   SERVED AT: /css/fleet.css (static file, no auth — pure presentation, no
 *              data). Self-contained: its own tokens/palette, nothing shared
 *              with any ArdinGate site's CSS (the monorepo cross-site
 *              isolation rule applies to CSS too).
 *
 * ARCHITECTURE:
 *   - CSS custom properties for the palette so the whole ops UI reads as one
 *     system. Dark control-room aesthetic (this is an internal ops tool, on
 *     screens all day) with a light-scheme fallback via prefers-color-scheme.
 *   - Categorical status colors are chosen for reasonable contrast AND are
 *     never the ONLY signal — status is always also carried by text, matching
 *     the dashboard's aria.decal colorblind-safe intent on the chart side.
 *
 * CHANGE LOG:
 * v1.0    2026-07-20  Claude  Initial fleet-ops stylesheet — topbar/nav, KPI
 *         stat bar, chart panel, widget grid, tables, forms, buttons, badges,
 *         login card; dark default with a light-scheme fallback.
 * v1.1    2026-07-20  Claude  Roadmap kanban board styles.
 *         - Five-column horizontally-scrolling board layout with per-column
 *           left-border color treatment (short/long/deferred/testing/shipped).
 *         - Draggable card face (title/excerpt/source badge), drag + drop-target
 *           visual states.
 *         - Add/edit modal overlay + actions row.
