Add /prototyping/journey-figures-gestalt.html

A single page showing all 18 journey section figures, grouped by
journey, with section title and caption beneath each figure. Lets
reviewers apply docs/journey-visualisation-rubric.md uniformly:
spot drift across the 18 at once instead of opening six tabs.

Layout: each journey is one block (heading + summary + 3-up
section grid). Section grid auto-fits at 280px minimum so the
trio sits comfortably side-by-side on desktop and wraps to a
single column on phones.

Index updated; entry sits next to the marginalia gestalt as the
twin design-review page.
