   LoneStarLower — content-page vocabulary (Task 4, P0.5)
   ----------------------------------------------------------------------------
   These patterns do not exist in the demo — it's a single-field app screen.
   The neighborhood template is 800+ words with tables, figures, and
   hierarchy (DESIGN_SYSTEM.md §6). Tokens only, same rule as components.css.

   NULL-STATE CONTRACT (DESIGN_SYSTEM.md §6, "does not exist yet" table +
   the rules immediately below it) — this is a template-authoring rule, not
   just a style, and it binds whatever templating engine P1a picks:

     1. A missing value REMOVES ITS COMPONENT ENTIRELY. Never render an empty
        stat, a dash, or "N/A" — it looks broken and gives an
        appraiser-skeptical homeowner a reason to distrust every other number
        on the page.
     2. A section with fewer than two populated stats does not render at all.
     3. The page must stay visually coherent at both extremes — the
        three-data-point minimum-viable page and the fully-populated maximum
        must both look deliberate, not like a template that broke. See
        shared/preview/ for both rendered side by side.
     4. This composes with seo/gates/check_data_density.py (built later, in
        P4) — a page falling below six data points is quarantined, not
        published thin. That gate doesn't exist yet; the contract here is
        what it will enforce against.

   None of the components below have a CSS "empty state" to style, on
   purpose — the correct empty state is DOM absence, so there is nothing to
   theme. What follows is only ever rendered with real data.
