The classic SVG-vs-text-baseline mismatch: body sets line-height: 1.7, which makes each text span's line-box ~24px tall while a 14–16px icon occupies just its own height. align-items: center then centers them geometrically, but the text's optical midline (x-height) sits below the geometric center, so the icon visually floats above the number. Collapses line-height to 1 on the three offending rows so the text's line-box matches the icon height: * EngagementSidecar (record explorer) * PostPreview's footer stats (replies / reposts / likes / quotes) * .profile-stat-item / .profile-join-date (profile previews) EngagementSidecar's icon span also gets display: inline-flex + alignItems: center as belt-and-braces in case any icon ships with its own line-box padding.
