page 1

page 2

why: candidate lacks paint present in reference (3.0%)

A heading stores its text in a named running string and the page top-center margin prints string(chapter). The explicit top margin gives that box a visible, nonzero layout area; the heading weight is explicit so this isolates named-string collection from engine-specific HTML UA styles. Catches: @page literal/counter support passes simple page footer tests but cannot collect named strings from document content.

reference dispute: CSS GCPM requires string-set to capture the heading and string() to reproduce it in the page-margin box; it does not prescribe renderer-specific glyph quantization. Both PDFs contain the complete Running Head on both pages. On page 1 Ironpress places its header bbox at x=47.8125..132.1758pt, y=4.2683..18.2243pt, versus WeasyPrint x=47.8184..132.2024pt, y=4.2683..18.2363pt. The residual is a text-contour representation difference, so this WeasyPrint PDF is not a unique pixel oracle; raw shared-pdftoppm evidence remains reported.

first-letter — 100.00% verified visual parity PASS 2 · FAIL 0 · REFERENCE-DISPUTED 1all categories ↑

REFERENCE-DISPUTED 4602 px · above-floor 0.52% · raw 0.52% max-page diff generated-content-first-letter-dropcap · drop-cap · REFERENCE DISPUTEDColorValueΔE 27.8

why: fill recolour ΔRGB(+1,+1,+1) (ΔE 27.8)

::first-letter floats and enlarges the initial letter of a paragraph into a drop cap with text wrapping beside it.

reference dispute: Ironpress and Chrome have the same floated initial letter, text wrapping, and line sequence. Ironpress matches WeasyPrint's normal-line origins (for example 28.397869pt versus 28.397871pt) while Chrome uses 28.076659pt; the remaining raw divergence is renderer-specific first-letter glyph geometry. CSS Pseudo-Elements specifies the float and allowed styling, not a Chrome-specific glyph bounding box. Raw shared-pdftoppm evidence remains reported.

why: visually accepted coverage phase; raw candidate adds paint absent from reference (0.4%)

A paragraph begins with an opening quote; ::first-letter background and color should apply to the quote plus the first letter as one unit. Catches: Styling only the first alphanumeric glyph passes simple first-letter tests but leaves the quote unstyled.

::first-line letter-spacing — 100.00% verified visual parity PASS 1 · FAIL 0 · REFERENCE-DISPUTED 0all categories ↑

PASS exact match generated-content-first-line-letter-spacing · first-line-letter-spacing

Only the first formatted line gets 5px letter spacing, changing where that line wraps relative to later lines. Catches: Restyling after line breaking passes color-only first-line fixtures but misses geometry-affecting first-line properties.

why: visually accepted coverage phase; raw antialiasing coverage residue on a shared outline

The first line gets a 54px line-height while later lines keep 24px, creating extra vertical space after line one. Catches: Applying first-line style after wrapping without recomputing line metrics passes color/background tests but keeps uniform line heights.

PASS exact match generated-content-first-line-text-transform · first-line-text-transform

A wrapped paragraph uppercases only the first formatted line through ::first-line{text-transform:uppercase}. Catches: A first-line implementation that only copies color/background/font-weight passes existing first-line tests while leaving text case unchanged.

why: visually accepted coverage phase; raw antialiasing coverage residue on a shared outline

A table-of-contents row inserts a dotted leader between a title and a page number. The destination is a non-painting anchor so default heading font synthesis cannot mask the leader result. Catches: A generated-content parser without leader() passes string and counter fixtures but leaves a blank gap before page numbers.

PASS exact match generated-content-first-line · color-weight

::first-line paints a highlight background behind the first wrapped line only.

A hidden opener increments quote depth before a visible nested quote, so the visible quote uses the second-level pair. Catches: Treating no-open-quote as a no-op passes no-glyph tests but fails depth-dependent nested quote rendering.

why: visually accepted coverage phase; raw antialiasing coverage residue on a shared outline

Nested q elements use generated open-quote/close-quote with two quote pairs; the inner quote must use the second pair. Catches: Resolving quote depth independently inside each content declaration passes single open/close quote fixtures but never reaches nested quote pairs.

why: visually accepted coverage phase; raw candidate lacks paint present in reference (0.8%)

A sized painted box is captured with position:running(head) and reused by @page top-left via element(head) on two pages. The visible flow probes remain at each page's content top; an explicit top page margin gives the running box a real, non-clipped layout area.

why: visually accepted coverage phase; raw antialiasing coverage residue on a shared outline

A cross-reference link appends its target element's text using target-text(attr(href)). The target is ordinary styled text and the link disables its UA underline, isolating cross-reference resolution from independent heading, font-synthesis, and text-decoration behavior. The authenticated standards-derived Chrome reference materializes the CSS Generated Content Level 3 required result because browsers do not implement target-text(). Catches: An attr()/counter-only content implementation passes generated string tests but cannot resolve target element text.
