polish: tighten spacing + visual refinements across all sections

- Reduced py-24 → py-20 on Services, Configurator, Process, Works, Philosophy
- TrustBar: py-16 → py-12, gradient bridge adjusted
- Services: pillar divider opacity increased (outline/20), header gap tightened
- Configurator: added subtle dividers between service cards
- SelectedWorks: darkened coming-soon text and border opacity
- Philosophy: confirmed 2px primary border on pillars
