 folder per gym (`/3070/`, `/<postal-code>/`), content rows carry `gym_id`, and the
 backoffice has an "a editar" gym switcher (`admin_gym_id()` /
 `admin_gym()` in `config/functions_gyms.php`). `/` and `/home` 301 to the default gym (`is_default`); the other published gyms appear as highlighted buttons (`.gym-switch-btn`) at the right end of the public navbar (`site/includes/navbar.php`). `site/gym_chooser.php` is no longer used.
+Each gym has a brand colour (`gyms.brand_color`, `#RRGGBB`, migration `migration_20261013_gym_brand_color.sql`; gym 1 = green `#C2D500`, gym 2 = red): set in Gestão → Ginásios, emitted as `:root` overrides by `gym_brand_css()` in `site/includes/include.php`. New components must use `--fitme-accent*` / `--fitme-on-accent`, never a hard-coded colour; the CrossFit nav pill follows the brand colour too.
 An unpublished gym 404s publicly but previews for staff.
