Description

What is the purpose of this pull request?

This pull request:

• propagates fixes merged to develop between 2026-08-11 and 2026-08-12 to sibling packages with the same defects.

Doubled period in C header doc comment (source: 10f021c)

Removes a doubled sentence-ending period from the C header doc comment in @stdlib/constants/float32/eps (include/stdlib/constants/float32/eps.h, line 23), which read "...floating-point number.." — the float64 sibling header already uses a single period. Found via a repo-wide scan for the same defect fixed in 10f021c, which corrected an identical doubled period in the @stdlib/stats/base/ndarray/dnanmeanpn header. No functional change; doc comment only.

JSDoc example indentation in TypeScript declaration files (sources: cb9723a, 7026843)

Fixes JSDoc example indentation in TypeScript declaration files, propagating the correction from cb9723a and 7026843 (merged to develop 2026-08-11), which fixed object-literal option keys indented four spaces after the comment asterisk instead of the conventional five (e.g. * 'dtype': 'generic' → * 'dtype': 'generic'). A repo-wide scan turned up the same defect in seven remaining declaration files; this corrects all 57 lines. The @stdlib/ndarray namespace declaration is generated by _tools/scripts/create_namespace_types.js from sub-package declarations, and its one affected line derives from ndarray/broadcast-scalar-like, fixed in this same commit, so the manual edit matches what the next regeneration will emit. Two remaining instances, in blas/ext/base/ndarray/ccopy-within and zcopy-within, are intentionally excluded — already fixed by open PR #14201.

• @stdlib/ndarray (namespace declarations, 1 line)

Other

Validation performed:

• Pattern signatures were scanned repo-wide (rg over *.h for doubled periods; over **/docs/types/index.d.ts for four-space option-key indentation, where 761 files use the five-space form).
• Each candidate site was independently verified by two full-file review passes, a verbatim-applicability pass, and a style-consistency pass against docs/style-guides and sibling packages fixed by the source commits.
• Deliberately excluded: blas/ext/base/ndarray/ccopy-within/zcopy-within (covered by open PR style: add missing spaces #14201); four-space @example function-body lines in ndarray/docs/types/index.d.ts deriving from ndarray/count-if (different construct — fix belongs in count-if at source); ..-terminated inline // comments in .js files (different context from doc comments).
