{# _splash.html — left pane of the auth shell.

   Precedence (first non-null wins):
     1. branding.splash_url        → sandboxed <iframe>
     2. branding.splash_image_url  → shader canvas with shape source "image"
     3. branding.splash_primitive  → shader canvas with shape source "primitive"
     4. else                       → shader canvas with shape source "text"

   Expected context:
     - branding (optional BrandingConfig)
     - application_name (optional — used as fallback for splash_text)
