/* ============================================================
   NSN MIL-SPEC SHARED THEME TOKENS — single source of truth
   ------------------------------------------------------------
   Consumed by:
     - isr41_v42_enhanced_10.html         (replaces inline :root at line 13
                                           and inline :root at line 991)
     - clients/authoring-app/index.html   (replaces clients/authoring-app/src/theme.css)

   Palette + typography + MIL-STD-2525D affiliation symbology.

   Provenance: NSNSIM-53 (2026-07-01) — merged from the two ISR42 top-level
   :root blocks. All values are ISR42-canonical (byte-identical to ISR42
   inline definitions at extraction time). The authoring app's earlier
   src/theme.css was a duplicate copy of the ISR42 line-13 block plus two
   extras (--font-mono, --fs-xl). Both extras are preserved in this file:
     - --font-mono: identical font stack to ISR42's --font-ui, exposed
       under the second name so existing authoring-app CSS (`var(--font-mono)`
       in 9 places in styles.css) continues to resolve without renaming.
     - --fs-xl: no usage in either client yet, kept for future demand.

   Deploy: served by Caddy under `/shared/*` (root: `/var/www/_shared/`).
   Both clients reference this file via absolute URL:
     <link rel="stylesheet" href="/shared/theme.css">

   To modify tokens: edit THIS file only. Do NOT reintroduce a per-app
   :root block that redefines these variables — that reintroduces the
   drift-risk this file exists to prevent. If a client-specific tweak is
   genuinely needed (e.g., a component-scoped variant), define a NEW token
   in the client's own layout stylesheet, do not shadow one defined here.

   Note: ISR42's @media (pointer:coarse) :root override at ex-line-1025
   is inseparable from its @media context and REMAINS INLINE in
   isr41_v42_enhanced_10.html. Not migrated.
