/* ==========================================================================
   baldur.sh landing — standalone stylesheet ("black premium" design
   language, 2026-08).

   This file styles the hand-authored landing (web/root/index.html) end to end:
   its own header/footer/skip-link plus the hero (code + incident log), the
   healing-ledger band, and the three-step band. It ships ONLY on the landing
   (served under /landing/), never on docs pages.

   Token drift note: the `:root` block below is the landing's own copy. The
   docs-surface chrome (web/overrides/assets/brand.css) keeps a minimal copy of
   the shared chrome tokens and re-authors the header-nav rules; a brand-look
   change touches both files. See brand.css's header comment.

   Design language: fully monochrome chrome — near-black ground, bone text,
   dark hairlines — with color living ONLY inside the product artifacts, and
   only two data hues: fail red and heal jade. The ledger's open-count series
   is neutral (never amber); code syntax is monochrome (weight and brightness,
   not hue). Same rule the admin console follows. Type: Schibsted Grotesk
   (self-hosted variable font) for display + body, IBM Plex Mono (self-hosted
   400/500) for code, logs, and data tokens.

   Alignment contract (do not change these values without changing brand.css):
   72rem content rail, 1.2rem side insets, header padding 0.85rem 1.2rem
   (57px height), wordmark 1.05rem, nav links 0.85rem at 1.2rem gap, GitHub
   icon 1.2rem, and the wide-viewport ramp below — brand.css maps the same
   pixels onto Material's 20px root so landing <-> docs never jumps.
