Walkthrough

Adds a new .editorconfig file setting repository-wide formatting rules: root = true, UTF-8 encoding, LF line endings, trim trailing whitespace, ensure final newline, default 4-space indentation, and file-type-specific overrides (2-space for JS/TS/shell, tab for Makefiles), plus explanatory comments.

Changes

Cohort / File(s)	Summary
EditorConfig Configuration /.editorconfig	Adds .editorconfig with root = true; universal settings (utf-8, LF, trim_trailing_whitespace, insert_final_newline); default indentation 4 spaces; overrides for Markdown (no trim), JS/TS/JSON/YAML (2-space), shell scripts (2-space), Makefiles/Mk (tab, tab_width=4); includes comments and links to docs.

Poem

🐰 A tiny file hops in place,
Spaces settle, tabs find grace,
UTF‑8 keeps every line bright,
LF and trim set formatting right,
Hop, code, hop — all files unite! 🥕

In @.editorconfig:
- Around line 22-86: The .editorconfig contains many per-file sections that
duplicate the universal [*] defaults; remove the entirely redundant sections
([*.{yml,yaml}], [*.json], [*.{js,jsx,ts,tsx}], [*.sh], [*.{toml,ini,cfg}] if
identical, [*.{xml,html,svg}], [*.{css,scss,sass,less}],
[{package.json,package-lock.json}]) and consolidate any needed overrides into
only the sections that differ from the universal [*] settings; for partially
redundant entries (e.g., [*.py], [*.java], [*.{c,cpp,h,hpp}],
[{*.gradle,*.gradle.kts}]) remove the duplicated indent_style or indent_size
lines so each section only contains settings that override the [*] defaults.

In @.editorconfig:
- Around line 29-34: Merge the two Makefile-specific sections ([Makefile] and
[*.mk]) into a single glob entry (e.g., combine into one bracketed section
covering both Makefile and .mk files) and add a tab_width setting (for example
tab_width = 4) alongside indent_style = tab so editors render tabs consistently;
update the existing [Makefile] and [*.mk] entries to a single combined section
and include the tab_width property.

Duplicate comments:
In @.editorconfig:
- Around line 21-23: The .editorconfig override
[*.{js,jsx,ts,tsx,json,yml,yaml}] currently sets indent_size = 2 but omits
common web markup/style file extensions, causing .html, .css, .scss, .sass,
.less, .xml, .svg to fall back to the [*] 4-space rule; update the glob in that
section (the bracketed pattern in .editorconfig) to include those extensions so
they inherit indent_size = 2 (or, if 4-space was intentional, add a clarifying
comment in .editorconfig explaining that divergence).

Inline comments:
In @.editorconfig:
- Around line 36-60: Remove the large property/glob reference block currently
embedded in .editorconfig (the explanatory block spanning the property and
file-pattern examples), keep the header link to editorconfig.org, and move the
full reference text into the repository README (or a new docs/ section) with the
same official links; update .editorconfig to be concise and focused only on
configuration declarations and a short pointer comment to the README for the
full reference.
- Around line 33-35: There are two extra blank lines breaking the
single-blank-line pattern between sections in the .editorconfig; remove one of
the blank lines so there is exactly one empty line separating configuration
sections (i.e., collapse the three consecutive blank lines down to a single
blank line) and ensure the file follows the one-blank-line convention used
elsewhere.
- Around line 21-27: The two identical override sections in .editorconfig — the
[*.{js,jsx,ts,tsx,json,yml,yaml}] block and the [*.sh] block — should be
consolidated so the single override covers both file sets; update the glob in
the JS/TS block to include the sh pattern (or otherwise merge the [*.sh] entry
into the existing override) and remove the redundant [*.sh] section so only one
indent_size = 2 override remains.
