SVG parts in realistic diagrams will always overlap.
A developer must accept this and use event delegation at the SVG level to manage interactions.
Realistic diagrams often have parts that overlap. For example, a bicycle bell sits on a handlebar. Trying to prevent this overlap makes the diagram look wrong. Do not attach pointer events to individual SVG groups. This causes flickering when the pointer moves between overlapping parts. Instead, use event delegation on the main SVG element.
A developer creates an interactive diagram of a bicycle. The bell and handlebar are separate SVG groups but visually overlap. If the developer attaches `pointerenter` and `pointerleave` to each group, the tooltip flickers when the user moves the pointer between the bell and the handlebar. The tooltip disappears and reappears quickly.

The user interface for Chapter 1 is the master design. All other chapters must use this design.
A developer must use `position: fixed` or `position: absolute` for an overlay pane. This makes the pane float above other content.
A developer must define a fixed total height for the main container. Every element inside this container needs a fixed slot.
All web pages must use the same brand colors. Do not create new color schemes.
