Root cause

A form label often paints its text through an inner carrier: <label class="field"><span class="field__label">Name</span><input></label>. The presentation graph resolves the label caption's typography from that carrier (#2209), but the label carrier list TYPOGRAPHY_PROPERTIES left out text-transform. Only the button-caption list (CAPTION_PROPERTIES, #2786) carried case. A provider label that renders the caption directly therefore lost text-transform: uppercase. The same list drives inherited text for in-form copy, so copy that inherits its case from an ancestor lost it too.

text-transform is an inherited text property like the others, so it belongs in the one list. With it added, CAPTION_PROPERTIES is identical to TYPOGRAPHY_PROPERTIES and is removed.

Before / after

Fixture 75 (/contact, Jetpack-mapped contact form, 1440px), label caption:

source  NAME / EMAIL / SUBJECT / MESSAGE   text-transform: uppercase
trunk   Name / Email / Subject / Message   text-transform: none
branch  NAME / EMAIL / SUBJECT / MESSAGE   text-transform: uppercase

The presentation graph for that label now reports "text_transform":"uppercase". Field geometry is unchanged and still matches the source.

Coverage

tests/unit/form-label-carrier-case.php (new, 4 assertions; all 4 fail on trunk):

• a label text carrier sets the caption case alongside its typography
• the carrier's case wins over the label's own case for the text it paints
• a conditional carrier case becomes a label variant
• in-form copy inherits its case from the nearest declaring ancestor

Test plan

• php tests/unit/form-label-carrier-case.php
• Full composer test suite (612 commands)
• composer topology-diff -- --baseline tools/topology-diff/baseline.json: topology matches the baseline
• Studio import of fixture 75 with this change; contact labels measured in Chromium
