Add phased rendering to the display list builder so that within each stacking context, block backgrounds/borders paint before floats, which paint before inline content, per CSS 2.1 Appendix E steps 3-5. Introduces a RenderPhase enum (BackgroundsOnly, InlineContentOnly, Full) threaded through render_layout_box_normal and render_non_inline_descendants. Step 6 positioned-auto descendants are collected and rendered via render_stacking_context for correct internal Appendix E ordering. Net +20 WPT tests passing (25 promoted, 5 demoted for pixel regressions). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
