Fixes #172.
Selector and Root containers currently discard their own
spaceswhen serialized. This loses formatting when constructing nested selectors and can changea .bintoa.bwhen a transform replaces a pseudo with its inner selector and transfers the pseudo's spaces.Honor the existing
rawSpaceBeforeandrawSpaceAfterproperties around container contents. Child spaces remain additive, raw spaces retain their usual precedence, and root trailing commas stay inside the surrounding spaces. Document these rules and cover construction, empty containers, cloning, nested pseudos, and replacement transforms.Validation on Node 24.22.0:
npm test: all 906 tests pass, including lint, type checking, build, and coverage gates (95.20% lines, 95.57% branches, 97.74% functions). Lint reports two warnings in the unchangedexceptions.mjs.oxfmt --check;git diff --checkpasses.OpenAI Codex assisted with the implementation, tests, and description.
