Reconcile text nodes when the child structure changes.
This branch only processes element children. A change from <text><tspan>old</tspan></text> to <text>new</text> removes the tspan but never applies new. The reverse change retains the old direct text beside the new tspan.
Reconcile childNodes, or replace the content when the next and current text-node structures differ. Preserve the required exit behavior when hooks are active.

I reproduced both transitions against the PR base (29ed879) and this branch, with identical failures. The same logic already exists in reconcile.ts and motion.ts; this PR extracts it into the shared reconciler.
This is a valid bug, but I'd handle it separately to keep this bundle-size refactor behavior-preserving. That fix should cover both text/element transitions and preserve deferred exit hooks.
Record starting TanStack-only measurements for a generic Vite application with line and pie charts. Baseline: 185,419 minified bytes; 60,868 gzip bytes; 52,085 Brotli bytes. Savings: 0 bytes (measurements only).
Consolidate horizontal and vertical tick, axis-line, and title layout while keeping orientation-specific geometry, label anchors, and margin measurement. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 185,419 -> 184,459 B; saves 960 B (0.52%). gzip: 60,868 -> 60,788 B; saves 80 B (0.13%). Brotli: 52,085 -> 52,071 B; saves 14 B (0.03%). Total savings from baseline: 960 B (0.52%) minified, 80 B (0.13%) gzip, and 14 B (0.03%) Brotli. Validation: core tests pass; production Edge scenarios produce identical SVGs to the baseline, including updates, keyboard tooltips, resize, and empty data.
Use the same bar entrance track for initial rendering and inserted data, and share transform entrance tracks between Cartesian and radial paths. Centralize motion-role cleanup and keyed-element attribute reads. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 184,459 -> 182,279 B; saves 2,180 B (1.18%). gzip: 60,788 -> 60,565 B; saves 223 B (0.37%). Brotli: 52,071 -> 51,974 B; saves 97 B (0.19%). Total savings from baseline: 3,140 B (1.69%) minified, 303 B (0.50%) gzip, and 111 B (0.21%) Brotli. Validation: TypeScript and motion tests pass. Production Edge scenarios render identical SVGs to the baseline, with animation, updates, keyboard tooltips, resize, empty data, and reduced motion exercised.
Share the keyed SVG tree walk between static updates, SVG tweens, and motion tracks. Keep the public reconciliation API unchanged, while motion imports the static path directly and no longer retains the separate tween engine. Preserve the existing resource replacement policy for each renderer. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 182,279 -> 179,361 B; saves 2,918 B (1.60%). gzip: 60,565 -> 59,535 B; saves 1,030 B (1.70%). Brotli: 51,974 -> 51,378 B; saves 596 B (1.15%). Total savings from baseline: 6,058 B (3.27%) minified, 1,333 B (2.19%) gzip, and 707 B (1.36%) Brotli. Validation: TypeScript, reconciliation, motion, and SVG surface tests pass; production Edge SVG snapshots match the baseline. Bundle boundary checks pass; a few locked non-motion consumer ceilings need a final baseline refresh for small gzip changes (up to 70 bytes).
Reuse stack row normalization and explicit/value-based series ordering for stack extents and exposed bar ends. Keep inside-out ordering and its existing paint-envelope behavior, and use the shared chart-value predicates. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 179,361 -> 178,524 B; saves 837 B (0.47%). gzip: 59,535 -> 59,341 B; saves 194 B (0.33%). Brotli: 51,378 -> 51,279 B; saves 99 B (0.19%). Total savings from baseline: 6,895 B (3.72%) minified, 1,527 B (2.51%) gzip, and 806 B (1.55%) Brotli. Validation: TypeScript, mark and stack tests pass; production Edge SVG snapshots match the baseline for all application scenarios.
Centralize motion callback defaults and semantic class precedence. Find the longest matching owner in one pass instead of allocating and sorting candidate arrays for marks, focus guides, scale lookup, and transition overrides. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 178,524 -> 177,432 B; saves 1,092 B (0.61%). gzip: 59,341 -> 59,238 B; saves 103 B (0.17%). Brotli: 51,279 -> 51,236 B; saves 43 B (0.08%). Total savings from baseline: 7,987 B (4.31%) minified, 1,630 B (2.68%) gzip, and 849 B (1.63%) Brotli. Validation: TypeScript and motion tests pass; production Edge SVG snapshots match the baseline, including updates, focus, resize, and reduced motion.
Share the concrete initialization code behind both mark factories, the Date/Object.is comparison used by scales and interactions, and numeric option policies. Keep rejecting negative values distinct from clamping them to zero, and retain the public mark factory signatures. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 177,432 -> 176,471 B; saves 961 B (0.54%). gzip: 59,238 -> 59,063 B; saves 175 B (0.30%). Brotli: 51,236 -> 51,143 B; saves 93 B (0.18%). Total savings from baseline: 8,948 B (4.83%) minified, 1,805 B (2.97%) gzip, and 942 B (1.81%) Brotli. Validation: TypeScript and all core tests pass, including focused coverage for fallback versus clamping, non-finite inputs, dates, and signed zero. Production Edge SVG snapshots match every baseline scenario.
Use one orientation-aware tick-label and grid node shape, share physical anchor resolution, and walk guide labels and rules with one translation-aware traversal. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 176,471 -> 176,268 B; saves 203 B (0.12%). gzip: 59,063 -> 59,054 B; saves 9 B (0.02%). Brotli: 51,143 -> 51,128 B; saves 15 B (0.03%). Total savings from baseline: 9,151 B (4.94%) minified, 1,814 B (2.98%) gzip, and 957 B (1.84%) Brotli. Validation: scene and guide-layout tests, TypeScript, and identical normalized SVGs in the browser scenarios.
Reuse squared axis distances for rectangular bounds and one radius-distance calculation for dots, strokes, and rounded rectangles. Remove a redundant segment-count clamp after empty and single-point paths have already returned. Generic Vite application, TanStack only, compared with the preceding commit: Minified: 176,268 -> 176,112 B; saves 156 B (0.09%). gzip: 59,054 -> 59,015 B; saves 39 B (0.07%). Brotli: 51,128 -> 51,044 B; saves 84 B (0.16%). Total savings from baseline: 9,307 B (5.02%) minified, 1,853 B (3.04%) gzip, and 1,041 B (2.00%) Brotli. Validation: nearest-point tests and unchanged browser SVG snapshots across updates, resizing, empty data, and reduced motion; keyboard tooltips pass.
Refresh universal and comparison measurements, source provenance, generated documentation and catalog previews, and add a patch changeset. Classify the extracted numeric, stack-order, and reconciliation helpers in the existing dependency-boundary checks. Calibrate isolated gzip ceilings for measured helper-sharing overhead: stack transforms +10 B, treemap +30 B, and the scale-value mark factory +8 B against main. Every locked universal entry is smaller in both minified and gzip bytes. Regenerated tooltip preview differences are weekday labels from the existing local-time formatter; geometry is unchanged. No additional TanStack runtime changes in this commit. Total savings from baseline: 9,307 B (5.02%) minified, 1,853 B (3.04%) gzip, and 1,041 B (2.00%) Brotli. Validation: tests, types, packed consumers, documentation, catalog, formatting, and bundle checks pass. Browser scenarios retain identical normalized SVGs and visually matching screenshots. The generic Vite TanStack chunk is byte-identical after restoring the original helper names, and all regenerated catalog SVGs match the previous output.

Reduce duplicated chart runtime code while preserving the existing APIs and behavior. In a generic Vite application with line and pie charts, the minified TanStack code is 5.02% smaller:
These measurements exclude application code, React, D3, and the bundler runtime. The measurement application is outside this PR. All locked representative bundle entries also shrink; a few small isolated entries grow by 8–30 gzip bytes because of shared helpers, with the affected ceilings adjusted accordingly.
Please review the commits individually. Each optimization has its own commit explaining the change and its incremental savings. The choice of rebase or squash when merging is entirely up to the maintainer.
This work was fully automated by Codex using GPT-6 Astra, including implementation, measurement, testing, and PR preparation. Only the final outcome was validated by a human; the implementation has not been human-reviewed.
