Prompt 01: Rename xxl to 2xl

Complexity: Moderate (false positive risk — xxl may appear as block IDs or custom data)

Goal

Rename all xxl breakpoint references to 2xl in Lowdefy YAML configs. This covers YAML keys, quoted string values, and bare values.

Scope

Search all .yaml and .yml files in the project (excluding . directories and node_modules).

What to Find

1. YAML keys -- xxl: at the start of a line (after optional whitespace). Examples: xxl:, xxl: { span: 4 }
2. Quoted strings -- "xxl" or 'xxl' as values (typically _media comparisons like _eq: [_media: size, "xxl"])
3. Bare values -- xxl as an unquoted value after - or : at end of line

How to Apply

For each file with matches:

1. Show the user every matching line with its line number and file path.
2. Ask the user to confirm no matches are false positives (block IDs, custom properties named xxl, or string data unrelated to breakpoints).
3. After confirmation, apply these replacements in each file:
   • xxl: key at start of line (preserving indent) becomes 2xl:
   • "xxl" becomes "2xl"
   • 'xxl' becomes '2xl'
   • Bare xxl after - or : at end of line becomes 2xl

False Positive Checklist

• A YAML key xxl: that is a block ID or custom property name (not a breakpoint override)
• A string value "xxl" stored as data (not a _media comparison)
• Any xxl inside comments (leave comments alone -- they are documentation)

Completion

Report the number of files modified and replacements made.
