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

A paragraph uses p::first-letter{initial-letter:2} to create a dropped initial spanning two lines without manual float sizing. Catches: A renderer with only custom ::first-letter font-size/float drop caps passes handcrafted drop-cap fixtures but ignores the initial-letter property.

PASS exact match typography-line-height-length · length

Length line-height 36px across three stacked lines to verify fixed line-box height.

PASS exact match typography-line-height-numeric · numeric

Unitless line-height 2 across three stacked lines to verify line-box spacing.

PASS exact match typography-line-height-percent · percentage-font-size

line-height:200% resolves from the element font-size to 40px line boxes; catches percentage line-height being ignored or inherited as 1.5.

PASS exact match typography-line-height-em-inheritance · line-height-em-inheritance

A parent sets font-size:20px and line-height:2em; a smaller child inherits a 40px computed line-height, not a unitless factor of 2. Catches: Treating line-height:2em as the number 2 passes simple same-element line-height tests but compresses descendants with smaller fonts.

A paragraph with a 42px span in the middle must produce a taller first line than the following normal line. Catches: A block-level line-height-only engine passes uniform line-height tests while clipping or overlapping large inline runs.
