+/* ============================================================
+ * Gruvbox dark theme
+ * ------------------------------------------------------------
+ * Project-owned theme overrides. The vendored `app.css` is a
+ * pre-compiled Tailwind + DaisyUI bundle and is NOT edited.
+ * This file is loaded *after* it (see base.html / admin/base.html)
+ * and only redefines DaisyUI's built-in `dark` theme.
+ *
+ * DaisyUI consumes each variable as `oklch(var(--x))`, so values
+ * must be OKLch "L% C H" triplets (no function wrapper). The hex
+ * next to each line is the source color it was converted from.
+ *
+ * Palette: https://github.com/morhetz/gruvbox  (dark, bright)
+ * To retune, change the hex, reconvert to OKLch, update the line.
+ * ============================================================ */
