/* ============================================================
   Helm — Landing page styles
   Builds on lib/tokens.css. Brand rules:
   - No shadows, no blur, no gradients inside components.
   - The wheel is the only thing that moves (plus very faint
     intersection-fade entrance for sections, kept subtle).
   - 0.5px borders. Gold is the only colored border.
