/* ============================================================================
   Impeccable — Neo Kinpaku kit (page-global primitives)

   Reusable component primitives lifted from /design-system so they work on
   every page. Brand lockup, section scaffolding, buttons, form controls,
   tabs, badges, tags, pagination, toasts, tooltips, modal, empty state,
   changelog, skeleton. No `.kinpaku-system-page` scope — drop these classes
   onto any element on any page.

   All values resolve through kinpaku-tokens.css. If a token name changes
   there, this file follows.

   Imported globally from Base.astro so every page picks them up.

   Site chrome (kinpaku theme) — shared header AND footer

   One definition for every kinpaku page, keyed off a single
   `.kinpaku-chrome` body class instead of a per-page selector list. A
   page opts into the dark-lacquer header + footer by adding
   `kinpaku-chrome` to its bodyClass (alongside any page-specific class);
   genuinely light pages (privacy, tutorials) simply omit it.

   This is the reusable unit: the header markup is Header.astro, the
   footer markup is Footer.astro, and everything visual lives here. Don't
   re-declare header/footer chrome in per-page stylesheets — the only
   legitimate per-page override is a deliberate brand moment (e.g. the
   home page's textured `body.home-kinpaku .site-footer`).

   Brand mark + wordmark mirror /design-system's .ks-brand / .ks-mark /
   .ks-wordmark exactly, so the header is internally consistent. The
   github pill and footer treatment used to be home-only / copy-pasted
   per page; they now live here so every kinpaku page matches.

   Kinpaku surface — legacy-token remap

   For pages whose content still reads the old light tokens
   (--color-paper, --color-ink, --font-display, …): instead of overriding

   the existing legacy CSS renders dark for free. This is the same trick
   docs-kinpaku/designing-kinpaku use per page, lifted into one reusable
   class. It is also the prototype for making kinpaku the global default —
   the eventual move is to lift this remap to :root and delete the light
   token values entirely.

   Pair with .kinpaku-chrome (header + footer). Existing bespoke kinpaku
   pages already remap in their own page stylesheet, so they don't need

   Live picker (kinpaku theme)

   Shared kinpaku styling for the .live-demo-* picker mock used on the
   homepage and /live-mode. The base structural CSS lives in
   site/styles/live-mode.css; this block re-skins the picker chrome
   (browser frame URL bar, bottom global bar, context bar, target
   outline, comment tag, stroke) on dark kinpaku surfaces.

   Page-specific bits stay in the page CSS:
     - .live-demo-frame background (lacquer-raised vs lacquer-deep)
     - .live-demo-stage (homepage shows a gold-grid stylized stage;
       /live-mode shows a light cream surface that simulates a real
       dev preview)
     - .live-demo-card (different content per page)

   To extend the picker to a new kinpaku-themed page, just add its body
   class to the selector lists below. No duplicating CSS in page files.

   The actual live picker that injects into user dev servers
   (skill/scripts/live-browser.js) is a separate runtime; its color
   constants are kept in sync with these tokens by hand.
