READ-2026-10-03 (Task 2-c) — site-wide typography/spacing baseline
Root cause (live computed-style audit of 8 representative pages):
the universal reset (*{margin:0;padding:0}) is never compensated for
bare /
// inside prose areas, so text renders flush:
paragraphs with 0px vertical margins (tool pages 3-5 of 6-8, home
175/178, /best/ 7/9, /guides/ 5/7), h2 margin-top 0 outside blogs,
classless left without marker indent. Blog pages carry their own
scoped typography block (inline .container-* rules) and are NOT
affected below: every rule here uses :where() = specificity 0, so any
existing class rule, inline style or page
