/* ============================================================
   OFY SUITE — GLOBAL BASELINE
   Single global stylesheet shared by every service. Per-service
   stylesheets (ofy-suite.css, ofy-paste.css, ofy-short.css,
   ofy-transfer.css, ofy-tools.css) layer additions on top.

   Architecture:
   - @font-face for self-hosted Inter Tight + JetBrains Mono (variable).
   - Tokens in oklch() — per-service hue switched by [data-service].
   - Light/dark via [data-theme="light"]; default is dark.
   - Subtle glass surfaces (header, .glass utility) as the only
     transparency in the system. Everything else is flat.
   - Motion gated by prefers-reduced-motion.
   ============================================================ */

/* ------------------------------------------------------------
   2026-05-26 — v2 canonical refresh (operator screenshots).

   ADDED (pure additions, no existing token renamed or removed):
     --bg-4, --bg-5          new dark surface levels (v2 studio uses these)
     --text-0..4             5-level hex text scale used by .v2-app surfaces
                             (dark-mode only; --fg-0..3 remain for light-mode-aware code)
     --accent-fg             near-white text for use on filled accent backgrounds
     --status-active         green active-state indicator (same hue as --status-ok, slightly different)
     --status-redirect       amber redirect-state indicator
     --status-planned        dim text for planned/future items
     --t-1                   pre-combined transition shorthand (--d-fast + --ease-std)
     --font-sans             alias for --ff-sans (consumed by v2.css classes)
     --font-mono             alias for --ff-mono (consumed by v2.css classes)

   NOT CHANGED (risk-mitigated):
     --bg-0..3 oklch values  unchanged — light mode compatibility
     --fg-0..3 oklch values  unchanged — light mode compatibility
     --line-1..3             unchanged — alpha-based, light mode compatible
     --r-1..3                unchanged — load-bearing across 37 templates
     Accent system           unchanged — per-service hue remains dynamic
