Elementor Variable Font Weight Patch

A temporary WordPress compatibility patch that fixes missing font-weight CSS on Elementor Global Typography presets built on registered variable-weight fonts.

The problem

Elementor's Global Fonts (Site Settings → Global Fonts) let you assign a font-weight to each typography preset. When the assigned font is a registered variable-weight font, Elementor adds a second "weight" slider control for the variable font-weight axis - but due to a bug in Elementor core, the resulting --e-global-typography-{id}-font-weight CSS custom property (referenced by widgets on the front end) is never actually defined anywhere.

The configured weight is saved correctly in the database and Elementor references the variable correctly - it just never defines it, so affected text silently falls back to the browser default weight.

This is tracked upstream as elementor/elementor#29496 and elementor/elementor#36009.

What this plugin does

It does not touch Elementor core. At render time, it reads the already-saved, correct values from the active Elementor Site Kit and prints the missing CSS custom properties so the browser can resolve them.

Specifically, on eligible front-end requests it:

1. Fetches the active Elementor Kit for the current request.
2. Reads system_typography and custom_typography settings and collects every preset with a typography_weight value (Elementor only populates that field for presets using a registered variable-weight font, so only affected presets are ever touched - no font list or preset-name matching required).
3. Sanitises each preset id and weight value.
4. Emits a compact :root { ... } block declaring both --e-global-typography-{id}-font-weight (the name Elementor's widget CSS actually references) and --e-global-typography-{id}-weight (seen in some existing manual workarounds), for drop-in compatibility with either naming convention.
5. Attaches that CSS as an inline style on the elementor-frontend stylesheet, falling back to a `
