/* Tenant Magnet. Smart Syndicator Brand Kit (Smart Syndicator Workspace CLAUDE.md): Ink + Sage, Inter only, flat (no shadows, no gradients), cards 7px.
   Sage #5A7A65 is the one accent (4.76:1 with white text). Text on tinted/grey surfaces and links use Sage Deep #3D5C48 (7.6:1).
   Kit's #B0B0B0 label gray fails 4.5:1 for text, so labels use the kit's Mid gray #6B6B6B (5.3:1 on white). */
