   vatds-restore.css
   -----------------------------------------------------------------------------
   RECONSTRUCTION FILE. A prior edit accidentally truncated the main
   `public/css/vatds.css` and a large chunk of VATDS-specific component styles
   was lost. This file restores those styles using ONLY design tokens from
   `public/css/variables.css`, and reuses the base component primitives from
   `public/css/main.css` (`.card`, `.btn`, `.badge`, `.table`, `.sidebar-item`,
   etc.) — see CLAUDE.md § "Frontend workflow" for the visual contract.

   These rules were written fresh from the EJS markup that uses them, so small
   cosmetic tweaks may be required after side-by-side comparison with CHub.
   Long-term plan: once every section here has been visually validated, merge
   the content back into `vatds.css` and delete this file. The <link> tag for
   it lives in `views/layout.ejs`, directly below the `vatds.css` <link>.

   Notes on the input list (`undefined-classes.txt`):
     - A handful of entries are NOT real class names — they are word fragments
       captured by the grep that produced the file (e.g. `body`, `row`, `num`,
       `center`, `code`, `dark`, `admin`, `facility`, `dashboard`, `rw`,
       `ize`, `lass`, `ount`, `tier`, `path`, `tr`, `ith`, `has`, `join`,
       `ins`, `ize`, `starts`, `position_type`, `metering`, `metering_enabled`,
       `is_on`, `writable`, `classes`, `class`, `num`). They are excluded.
     - `ids-atis-cell-`, `ids-atis-flow`, `ids-empty`, `rwy-card-`, `pos-type-`,
       `badge-`, `ids`, `pinned`, `airport`, `checklists`, `references`,
       `positions-grid`, `position-ids-items`, `has-visible-chart` — these
       are either already defined in `vatds.css` (ids-*) or added below.
     - Tokens referenced: --card, --border, --foreground, --muted-foreground,
       --brand, --brand-muted, --brand-subtle, --brand-ring, --sidebar,
       --sidebar-foreground, --sidebar-accent, --sidebar-border,
       --sidebar-muted-foreground, --secondary, --muted, --radius, --radius-sm,
