Migration: Drop content* Prefix from Layout Properties

Context

Layout properties were previously namespaced with a content prefix to distinguish content-area config from block-level config. The new grid system removes this distinction — the prefix is dropped.

Note: contentGutter is already handled by prompt 02 (renamed directly to gap).

What to Do

Apply these renames in all YAML files:

No user confirmation needed — these renames are unambiguous. The content* property names do not exist in any other Lowdefy context.

Files to Check

Glob: **/*.{yaml,yml} Grep: contentAlign:|contentJustify:|contentDirection:|contentWrap:|contentOverflow:

Examples

Before

- id: main_layout
  type: PageHeaderMenu
  layout:
    contentAlign: middle
    contentJustify: center
    contentDirection: column
    contentWrap: nowrap
    contentOverflow: auto

After

- id: main_layout
  type: PageHeaderMenu
  layout:
    align: middle
    justify: center
    direction: column
    wrap: nowrap
    overflow: auto

Edge Cases

• Do not rename inside string values, operator expressions, or code blocks
• Only rename YAML keys (at the start of a line after whitespace), not values

Verification

grep -rn 'contentAlign:\|contentJustify:\|contentDirection:\|contentWrap:\|contentOverflow:' --include='*.yaml' --include='*.yml' .

Should return zero matches.
