/* ===== LANDING.CSS =====
   Single-use stylesheet for views/landing.ejs.
   Loaded AFTER common.css so token vars are available.
   All selectors are `.ls-*` prefixed to avoid colliding with
   admin.css, builder.css, or main.css.

   Colour notes:
   - Body copy uses var(--color-grey-dark) (#333) — matches the app's
     default body-text token and meets WCAG AA on white at body size.
   - #111 is used for nav text, brand wordmark, and serif display
     headlines; per CLAUDE.md this is the allowed "darker than
     grey-dark" emphasis exception, mirroring how main.css uses it for
     active headings.
   - #eee is used for in-card hairlines (deliberately lighter than the
     default --color-grey-border = #ddd, which separates section
     surfaces from the page).
