/* =========================================================================== Teletoken — design tokens --------------------------------------------------------------------------- The palette has TWO POLES and they mean different things. Cool (signal) is the machine: telemetry, interactive affordances, anything the pipeline does by itself. Warm (ember -> alarm) is a finding: something a person should look at. Nothing is warm for decoration, so warmth on this screen always carries information. That is the whole concept — this pipeline is 87% noise, so the ground stays quiet and cool and the rare signal is unmissable. Light mode is NOT an inversion. Per Apple's guidance, the two appearances are designed separately and each re-checked for contrast: in dark, raised surfaces get LIGHTER than the page; in light they stay white while the page goes cool grey, so elevation reads correctly in both. ========================================================================= */ :root { /* ---- type ------------------------------------------------------------ Apple's Dynamic Type scale, adapted for desktop density.

Used on exactly two things: the login wordmark (.gate__word in auth.css) and the page title (h1.t1 in base.css). PREFER NOT TO PUT A NUMBER IN THIS FACE. Space Grotesk's digits are PROPORTIONAL by default — 452/1000 em for "1" against 648 for "0" — so a figure that ticks reflows the text around it and a figure cannot be compared with the one above it. The subset does keep tnum, and body sets font-variant-numeric: tabular-nums globally, so a digit that reaches this face lands on a uniform 620/1000 em rather than breaking the line. That makes the rule a preference rather than the hard prohibition the serif before it needed. It is still the rule: the vitals strip's big numbers, every metric, every table cell and every chart label stay in --f-sans, because a display face carrying data is the thing this type system is built to avoid. It is also a SINGLE 700 WEIGHT, the only master in the subset. Anything that asks it for 400, 500 or 600 gets a synthetic face unless `font-synthesis: none` is in force — it is, on html in base.css — and a real 700 only because .gate__word and h1.t1 both restate the weight.
