Most legacy systems fail not because of one flaw, but because of incoherence.
Semantic HTML, predictable DOM, accessible navigation.
Components that behave the same way every time.
Rendering that feels stable, fast, and intentional.
Titles, descriptions, and canonical tags that don’t mutate.
Patterns that reduce cognitive load and support assistive tech.
---When a system is coherent, users trust it.
Teams trust it.
Organizations trust it.
