Problem

Canonical conversion can preserve visible declarations while destroying the source selector target. Fixture 37 demonstrates two generic cases: .roster-card .stamp source spans become marker-only <mark> nodes without the author class, and a.view / layout-bearing non-button anchors become paragraph wrappers whose inner anchor lacks the source class. Hover, pseudo, descendant, and future stylesheet rules become inert.

Work

• Preserve safe source class/id/data identity on representable RichText inline nodes.
• Preserve non-button anchor identity on the inner <a> while retaining wrapper presentation where Gutenberg requires it.
• Use a semantic carrier only when structural display/alignment cannot be represented on the inner anchor.
• Rewrite selectors only when source DOM identity cannot be preserved.

Acceptance

• .roster-card .stamp and .roster-card a.view still select the intended saved node.
• Hover/pseudo/descendant variants remain effective.
• Inline-flex non-button anchors retain display, alignment, gap, href, and class.
• Gutenberg parse/save validation and canonical site-plan tests pass.
