Flatten marketing paths ahead of wiring up the websites

Drop the redundant documentation/marketing/ nesting inherited from the
plugin repos, so files sit at marketing/<plugin>/<page>.md. These paths
become raw URLs pasted into Elementor pages and ACF fields, so they are
much cheaper to change now than once sites reference them.

Fixes the four cross-plugin links for their new depth, and corrects the
README, which still pointed at the abandoned per-repo documentation/
folders instead of this repo.

+# Dark Mode Toggle
+
+A one-click, site-wide dark mode switch — using the colour palette you've already built in Elementor.
+
+## The problem it solves
+
+Dark mode is one of the most-requested features on modern websites, but building it properly usually means maintaining a whole second stylesheet, or wiring up custom CSS variables by hand across every template.
+
+## How it helps
+
+Dark Mode Toggle works directly with Elementor's own global colours — no separate stylesheet, no custom code. Add the toggle anywhere on your site, choose a dark palette, and one click flips your entire site into dark mode instantly, remembered for that visitor on their next visit too.
+
+Crucially, it speaks **both** of Elementor's colour systems:
+
+- The **classic Global Colors** (Primary, Secondary, Text, Accent) that traditional widgets use.
+- The **newer Elementor 4.x global variables** used by the latest atomic widgets.
+
+Real sites are increasingly a mix of the two, so the toggle can remap both at once — meaning your dark mode stays complete as you build with newer Elementor widgets, not just the old ones.
+
+## The result
+
+A genuine site-wide dark mode, built entirely from colours you already control through Elementor — future-proofed for the newer widget system, with nothing extra to maintain.
+
+*Note: this widget relies on your theme and Elementor Kit consistently using Elementor's global colours and variables throughout your design — the more consistently they're used, the more complete the dark mode effect will be.*
