/* Semantic Integrity Lab -- static stylesheet. No external fonts/CDNs
   (self-hosted only, matches CSP default-src 'self'). System font stack
   for speed and native feel on every platform. */

/* Utility classes -- used instead of inline style="" attributes
   everywhere in this app's templates. Deliberate: this CSP's
   `style-src 'self'` (no 'unsafe-inline') means an inline style
   attribute is silently dropped by the browser rather than applied --
   using classes here is a correctness requirement, not just tidiness
   (an earlier draft used inline styles for the hero logo's sizing,
   which the browser then ignored, rendering the image at its full
   natural size -- exactly the "logo takes over the page" bug this was
   built to fix). */

/* Futuristic space backdrop -- pure CSS, no images, no JavaScript
   (matches CSP script-src 'none'). Three layers:
     1. `html`'s own background -- static "planet" glows, calm, never moves.
     2. `.spacefx-stars` -- a fixed, viewport-covering starfield that
        slowly drifts (GPU-cheap background-position animation, not a
        layout-affecting one).
     3. `.spacefx-ship` x2 -- small CSS-drawn craft that cross the sky
        occasionally on a long, slow, looping path.
   All decorative: aria-hidden, pointer-events:none, and fully disabled
   under prefers-reduced-motion so this never fights an evaluator's own
   accessibility settings. Real content sits in its own stacking context
   above this layer (see header/main/footer `position:relative`). */
