ui/tokens.css is no longer a hand copy that drifts: scripts/fetch-tokens.sh takes the server's tokens.css at a git ref and tokens.lock.json pins it, as fetch-cli.sh does for the CLI. build.rs reads the two themes' --bg and --border out of it, so no colour is written in Rust. The content view reports the page's theme by a navigation the app refuses (llembas-theme:<name>), and the window, the title bar and the first-run page are painted in it and remember it.

# Put the LLeMbas server's design tokens where the app's own pages read them from:
|
|
# ui/tokens.css (a copy of the server's static/css/tokens.css, never edited by hand)
|
|
#
|
|
# scripts/fetch-tokens.sh <server-ref> copy the tokens at that ref (a tag such as v1.3.0,
|
|
# or HEAD) and write tokens.lock.json
|
|
# scripts/fetch-tokens.sh verify: ui/tokens.css matches tokens.lock.json
|
|
#
|
|
# The server is a git checkout, LLeMbas beside this repository by default (LLEMBAS_SERVER names
|
|
# another). The one change made to the copy: the @font-face rules are left out, with the comment
|
|
# above them. They name woff2 files the server vendors and the app does not carry; the app's pages
|
|
# fall through the same `--font-ui` stack to the system's monospace face, and without the rules
|
|
# the webview does not ask for two files that are not there.
|
|
#
|
|
# tokens.lock.json records the ref, the commit it resolved to, and the SHA-256 of ui/tokens.css
|
|
# as written, which is what verify checks. Like fetch-cli.sh and lembas-cli.version: the file in
|
|
# the tree says which server version the look comes from, and CI refuses a copy that drifted.
