/* ============================================================
 * rustio-admin / themes / dark
 *
 * Dark mode — soft graphite, never near-black.
 *
 * RustIO's dark theme is a calm nighttime workspace, not a hacker
 * terminal. Page bg and surfaces sit on a desaturated blue-graphite
 * scale (~hsl 218°) that lifts in 4–5% steps; depth comes from
 * layering, not shadows. No #000, no #111 — the floor is #2B313C.
 *
 * Tokens are duplicated under both `prefers-color-scheme: dark` (for
 * users who never touch the toggle) and `[data-rio-theme="dark"]`
 * (for explicit overrides) so the cascade is symmetric.
 *
 * Dark mode color tuning — three deliberate shifts vs. the light
 * palette:
 *
 *  1. Accent is lifted from `#0F8C7E` (light teal-emerald) to
 *     `#3FAA9D` (mid teal). The deep light-mode teal disappears into
 *     the graphite surface (~1.4:1 contrast); the lifted variant
 *     pops (~3.2:1) while keeping the same hue family so the brand
 *     reads identically across modes. White-on-accent stays above
 *     4.5:1 (passes WCAG AA body text).
 *
 *  2. Danger is shifted from `#F87171` (Tailwind red-400, reads
 *     pink-pastel on graphite) to `#DC4444` — a serious, saturated
 *     red that actually communicates destructive intent. White on
 *     it hits 4.7:1 (passes AA body), good enough for the solid
 *     "Yes, delete" button that uses it as background.
 *
 *  3. `text-strong` is pushed to pure `#FFFFFF` so page titles
 *     stand clearly above the `#F3F4F6` body. Without that gap
 *     the two reads as one tone.
