/* ============================================================================
   K9LogPro — Canonical primitive library (UI overhaul epic #835, Phase 3, #842)
   ----------------------------------------------------------------------------
   The single, Bootstrap-INDEPENDENT `.k9-*` component layer — the ~12 doc-25 §5
   primitives + the chart sub-primitives + the recurring composite blocks. This
   is the reusable vocabulary Phase-4 page restyles adopt.

   ARCHITECTURE (locked, doc 25 §8.4 Phase-3 decision):
   1. Purely ADDITIVE. Defining `.k9-*` classes changes the appearance of ZERO
      existing pages — nothing today carries a `.k9-*` class except the gallery
      at /admin/design-system. Bootstrap stays for the grid / utilities / JS only.
   2. Token-driven. Every color references a `--k9-*` custom property from the
      Phase-1 token sheet (css/k9-design-system.css) — never a raw hex / rgb()
      literal (pinned by Design_system_stylesheet_uses_tokens_not_raw_hex). One
      theme switch ([data-bs-theme]) recolors the whole layer.
   3. Zero-leak / single-vocabulary. EVERY selector is `.k9-*`-scoped — no bare
      element selectors (`button`, `table`, `input`) and no Bootstrap-class
      selectors (`.btn`, `.card`, `.badge`). A bare/Bootstrap selector would leak
      onto existing pages and break guarantee #1 (pinned by
      Primitive_layer_is_namespaced_and_does_not_restyle_bootstrap). Interactive
      primitives that are usually <button>s reset their own border/background/font
      so they never depend on a global element reset.

   Loaded from App.razor AFTER k9-design-system.css (so it sees the tokens) and
   BEFORE app.css. The Phase-1 `--bs-*` bridge is the PERMANENT Bootstrap↔token
   integration layer (NOT a removable shim) — Phase 4 shipped every page, yet the
   app deliberately keeps `.form-check` / `.alert` / grid + utilities on Bootstrap,
   so the bridge keeps that markup on-palette forever. See doc 25 §8.4 / #901.

   A11y (doc 25 §7): every interactive primitive shows a visible accent focus ring
   (:focus-visible); status colors pair with a text label + dot (color is never the
   only signal); hover-lift + skeleton shimmer honour prefers-reduced-motion. Both
   light and dark verified via the gallery.
