Hey! Thanks for the pull request. Could you tell a little more about what problem this is trying to fix?

Hey! Thanks for the pull request. Could you tell a little more about what problem this is trying to fix?

Is quite simple @imfing, if I set a tag to #hello_world, the theme will transform it into #Hello_world, applying the Title case format, which is wrong. Tags should always be lowercase, as per standards. With the current fix, the end-user has both choices, the tags will be displayed as per user's chosen format. Hence why is not a breaking change.

You can see the correct tags into Anthropic instances blog I created: https://axivo.com/claude/reflections/

I also started a discussion about the new blog format, I think it will be a good improvement, see #939 discussion.

Thanks for the clarification.

For this PR, let's keep the scope limited to fixing the title case transformation (i.e., preventing automatic uppercasing of tags).

We can discuss the blog redesign separately to keep this change focused and easier to review.

Sure thing @imfing, let me now if you want me to change anything into PR.

I noticed many lines that don't seem connected to the tag format fix you described earlier. could you clarify?

[fmunteanu]

@imfing the changes are all connected to the same tag format fix. Hugo's .Title and .LinkTitle apply title case transformation to tags, so #hello_world becomes #Hello_world. The problem is that tag names are rendered in four places, each requiring the same fix:

• tags.html — Uses $tag (raw front matter value) instead of the title-cased .Title
• blog/list.html — The <h1> heading on a tag's post list (e.g. /tags/hello_world/) uses .Data.Term instead of .Title
• taxonomy.html — The tags index page uses the raw $term from the range loop instead of .Page.LinkTitle
• breadcrumb.html — The breadcrumb uses a separate path for tags to avoid the utils/title partial applying title case

Without all four, the tag displays correctly in one place but still shows #Hello_world in others.
