/* The bundle — "The Letter" components (Oct 2026). THE app standard.

   Lifted verbatim from the hub at /app/ (templates/web/app_home.html), which
   is the north star: warm paper, one burgundy accent, Fraunces for voice,
   mono eyebrows, hairline rules instead of boxes. Tokens live in
   twb-tokens.css (--lt-*); the living styleguide is /app/design-system/;
   the rules are DESIGN_SYSTEM.md → "The Letter".

   Everything is scoped under `.lt` — wrap a page's content in
   <div class="lt"> and these apply; nothing leaks onto pages that don't.
   Linked globally from web/base.html.

   Sections marked (hub) are on /app/ today. Sections marked (extension) are
   derived from the same grammar for inner pages — keep them in that grammar. */
