fix(visual): make founder quote visible in visual regression snapshots

- Set reducedMotion:'reduce' on all visual regression projects.

- ScrollReveal/StaggerReveal now render visible by default.

- Scroll to bottom then top in waitForPageStable before screenshot.

- Add L2 element snapshot for founder-quote-section.

- Redesign quote as light card (bg-bg-primary/95) with ink text.

- Verified: type-check ok; lint 0 errors; visual:update 23/23.
