Guided /demo walkthrough

A no-signup guided walkthrough that takes a first-time visitor straight from the homepage to running a real solve, showcasing the platform's headline capability before ever asking for an account.

• You're evaluating DekEn for the first time and don't want to register yet
• You're demoing the platform live to a colleague or client
• You want the fastest path to 'see it actually compute something'

Steps a visitor through a fixed scripted path — load a small network, hit Run, read the result — using the same live solver a signed-in user gets, not a canned screenshot.
