 * The values are not here. Every token this file used to declare lives in
 * tokens.css, which is linked first and which both surfaces share; they were
 * moved after being checked identical one by one (`--bg`, `--ink`, `--accent`,
 * the six type sizes, the four corner steps), so the deletion could not change
 * a value. What stays here is the shell: layout, structure, components. Density
 * is still overridden below, because a user setting is not a token.
 *
 * Components below use var(--…) exclusively; a literal hex in a component is a
 * bug, and there is a test that greps for one.
 *
 * Direction: obsidian, flat, restrained. No glass and no glow — both were here
 * and both are gone. The accent is lime and it is reserved for *action and
 * state*: a button you can press, a status that is live, the screen you are on.
 * Everything highlighted means nothing highlighted, which is how a premium tool
