/* appdev.jaszberenyi.com — one stylesheet for the studio home, the app pages and the text pages.

   Family: this site shares its look with jaszberenyi.com (trapie/jaszberenyi-webpage) and
   thesuitwhobuilds.com (trapie/thesuitwhobuilds-site): Playfair Display / Inter / JetBrains Mono,
   a sticky glass nav with the IJ monogram, pill buttons, mono eyebrows and kickers, serif
   headlines, graph paper, a drawing sheet with a title block.
   - Daylight side (studio home, privacy, support, 404) = jaszberenyi.com: warm paper, ink,
     blueprint navy, amber / coral / teal.
   - Night side (the app landing pages) = The Suit Who Builds: charcoal, chalk, thin stripes.
     Each app keeps its own world on top of it: Ground Control the night sky and runway lights,
     Rocky Courier the warm cave.

   House rules that differ from the two sibling sites, because the apps are "Data Not Collected":
   - no third-party request of any kind: the three fonts are self-hosted (assets/fonts/, SIL OFL),
     and public/_headers enforces it with a self-only Content-Security-Policy;
   - no JavaScript: every effect here is CSS, and every one has a prefers-reduced-motion off-switch;
   - no inline style attributes (the CSP has no 'unsafe-inline').
   Performance rules carried over: glows are radial-gradients, never filter: blur(); only
   transform/opacity animate. */
