Replace language-specific CSS variables (--c-*) with a shared neutral color palette (--code-*) that can be reused across different syntax highlighters. This reduces duplication and makes it easier to maintain consistent colors across C, Ruby, and future language highlighters. Changes: - Add --code-cyan and --code-gray to neutral palette - Remove --c-* semantic variables for C highlighting - Update .c-* classes to reference neutral --code-* variables
Add a simple shell/bash syntax highlighter for documentation code blocks. The highlighter is focused on command-line documentation rather than full bash scripts. Highlights: - $ prompts (gray) - Commands/executables - first word on line (blue) - Options like -f, --flag, --option=value (cyan) - Single and double quoted strings (green) - Comments starting with # (gray, italic) The highlighter targets code blocks with language classes: bash, sh, shell, console. Files added: - lib/rdoc/generator/template/aliki/js/bash_highlighter.js - test/rdoc/generator/aliki/highlight_bash_test.rb

The current bash command code blocks are highlighted inconsistently because some code blocks got detected as Ruby, so Ruby highlighting is applied. This has been addressed in #1538.
But after the PR, we don't have any highlighting for bash, which I think we can provide rather simply.
With this PR, we can highlight code blocks tagged as
sh,shell,bash, andconsolewith a simple JS highlighter.
