/* SAES report generator — interface styles.
   No framework and no build step: this host has neither node nor npm, and the only
   JavaScript the app needs is the browser-side photo resizer. */

/* ---------- colour ----------
   Two independent axes, so neither has to know about the other:
     data-palette  which hue the interface is built around
     data-theme    light or dark (absent = follow the operating system)

   A palette supplies a light and a dark value for everything it touches, as -l / -d
   pairs. The blocks further down resolve those pairs to the tokens the components
   actually use. Adding a palette therefore means adding one block of data, and no
   component CSS changes at all.

   The neutrals shift with the palette rather than staying grey — a slate interface with
   green-tinted paper reads as a mistake. Only the accents and the paper move; the
   semantic colours (amber for caution, rust for alarm) stay put, because a warning must
   not change meaning when someone changes the colour scheme.

   None of this reaches the PDF. The document is SAES green and always will be — the
   brand is fixed, and only the tool around it is adjustable. */
