/* ==========================================================================
   SUITE SETTINGS — the shared two-column settings window shell
   Version 1.0.0 (2026-10-02). Served live by the hub at
   `http://127.0.0.1:4040/suite-settings.css`, next to `suite-ui.css`.
   One `<link>` per application:

     <link rel="stylesheet" href="http://127.0.0.1:4040/suite-settings.css" />

   WHAT THIS FILE IS
   The suite's ONE settings-window chrome. Every application opens its
   settings as a separate window (`?view=settings`) rendering the shared
   `SettingsWindow` shell from `@suite/settings`: a header, a left section
   nav and a scrollable right content column (the Kor panel pattern,
   centralized). A structural change is one edit in this file; every
   application inherits it on reload. No vendored copies.

   WHAT THIS FILE IS NOT
   The row/group/switch primitives INSIDE the content column — those are
   `suite-ui-group` / `suite-ui-row` / `suite-ui-switch` from `suite-ui.css`,
   reused as-is. Only the window shell lives here.

   ALL colors derive from the suite theme tokens (suite-theme.css); nothing
   is hardcoded, so light/dark and per-app accents flow in for free.

   THE CLASS CONTRACT (v1)
     .suite-settings-window        the window root: fills the viewport, column flex
     .suite-settings-header        48px title bar with hairline bottom
       .suite-settings-heading     the title cluster (title + subtitle)
         .suite-settings-title     "Settings" (13px/600)
         .suite-settings-subtitle  the application name (11px, tertiary)
       .suite-settings-close       the close button (16px icon hit area 28px)
     .suite-settings-body          the two-column row (flex:1, min-height:0)
       .suite-settings-nav         224px left nav, hairline right, scroll-y
         .suite-settings-nav-item  one row (32px, radius, hover/active accent)
           .suite-settings-nav-icon   leading 16px icon slot
           .suite-settings-nav-label  the row text (ellipsis)
       .suite-settings-main        right column (flex:1, min-width:0, column)
         .suite-settings-content   scrollable content pad 20/24, max-width 760px
         .suite-settings-footer    optional hairline-top footer strip
     .suite-settings-input         shared text input (rows)
     .suite-settings-select        shared select (rows)
     .suite-settings-textarea      shared textarea (rows)
     .suite-settings-back-link     small link-style action (rows)

   RULES (suite-ui precedents)
   - Light DOM only: no shadow roots, no bare-element selectors, no !important.
   - Theme flows from suite-theme.css tokens; this file never recolors them.
   - Defensive layout: the nav collapses to a horizontal scroll strip under
     640px — nothing wraps, overlaps or clips, and the content column keeps
     its scroll regardless of section count.
