pdftotext is a false oracle for emoji: Skia preserves the Unicode in the text cluster even when the glyph drew as .notdef tofu, so extraction passes on a broken render. The gate instead asserts (1) pdffonts shows an emoji family embedded and (2) pdftoppm rasterizes the page to color (measured ~1650 saturated pixels vs ~0 for tofu). pdfimages is not used: macOS embeds color emoji as Type 3 fonts, so it lists nothing even on a correct render. Adds resolvePopplerTool() (DRY resolver, returns null for clean skips) and a fixture exercising FE0F variation-selector emoji. Skips cleanly when poppler tools or a color-emoji font are unavailable.

# Emoji rendering gate 😀
|

|
||
This fixture exists to prove that emoji code points render as real color
|
||
glyphs in the output PDF, not as `.notdef` tofu boxes (▯).

|
||
Color emoji on one line: 😀 ❤️ 🚀 ✅ 💡
|
||
|
||
A variation-selector sequence (FE0F) renders color: ❤️ — the bare code point
|
||
❤ is text-style. Both must come from a font in the cascade, never tofu.

Non-emoji Unicode (unchanged, regression guard): em dash —, times ×, arrow →,

bullet •, ellipsis …
