img.has-text-siblings forced vertical-align: baseline on every inline
image with text siblings, out-specifying a book's own value (for example
a CJK glyph-substitution image nudged with vertical-align: -0.15em).
Because baseline is the CSS initial value, the declaration only ever
mattered when it clobbered an authored value.
Keep baseline as a default only: move it to a new
has-text-siblings-baseline class that applyImageStyle adds only when the
image has no author-set vertical-align (detected via getComputedStyle).
Refactor applyImageStyle to a two-phase read-then-write pass to avoid a
getComputedStyle-after-write style recalc.
