Crate makeover_webview 

The webview renderer for makeover_layout.

The renderer that needs no palette

makeover-immediate and makeover-tui both take a Palette, because egui and a terminal need an actual colour before they can put anything on screen. A webview does not: var(--surface-raised) is the late binding, and the browser resolves it against whatever themes.js last wrote onto :root.

So this crate emits text naming intents, and never learns a colour. It is the deferral rule with no adapter in the way, and it is why the webview was always the wrong renderer to derive a vocabulary from: it can express anything, so it never pushes back.

Phase A: the stylesheet only

This emits component CSS and no markup, deliberately. GoingsOn has 145 innerHTML sites and Balanced Breakfast 175 createElement sites; moving markup is a migration, while adopting a generated stylesheet is a deletion. The apps keep every line of their markup and gain the classes.

The output is byte-identical to the bevel composition both apps already hand-write, which is asserted below, so adoption removes duplicated lines rather than changing a pixel.

Substitution, three ways

Fill::Well has no colour on makeover before 2.3.0, and each renderer answers that differently, which is the evidence that dropping Fill::fallback from the description was right:

• makeover-immediate substitutes the page in Rust.
• makeover-tui refuses to substitute and draws an edge instead, because a terminal would quantise the two together.
• here, CSS already has the mechanism: var(--surface-well, var(--surface-page)) falls back in the browser, and nothing in Rust decides anything.
