Sizing page, generated

[nathanacurtis]

Problem

Variables scoped to sizing properties are emitted and never shown.

Scope

• Generated from the emitted variables, filtered to sizing-scoped properties.
• Emitted as stories into the platform tree.
• Shares the scale-visualization decision with the spacing page — do not invent a second form.

Acceptance criteria

• Page lists every sizing-scoped variable with its resolved value.
• Collections and modes are distinguished.
• Visual form matches the spacing page.
• Regenerating after a library change updates the page with no hand editing.

Case data

• Territory: cli
• Size: s
• Wave: 2
