TYPOGRAPHY

/*
Google Fonts import — add to index.html :
Rationale: DM Sans has optical sizing, a friendly rounded geometry that reads
as "human and modern" rather than clinical. It handles both display and small
body text cleanly — avoiding the need for a second font load, which keeps
performance tight on mobile. The wide weight range (400–700) covers all UI states.
