/*
 * Pulso's website — one stylesheet for all four pages.
 *
 * Transcribed from the "Pulso Website" design in the Pulso project in Claude
 * Design (and its three sub-pages). The desktop sizes are the design's own at
 * two-thirds: Claude Design shows its canvas at that scale, so its raw numbers
 * render half as large again in a browser (the owner's catch, 2 Nov 2026). The design was drawn for a wide screen only; everything under the
 * `max-width` blocks at the bottom is what makes it fit a phone, added on the
 * owner's ask of 2 November 2026.
 *
 * The font is served from this folder rather than from Google Fonts. Loading
 * it from Google hands every visitor's IP address to Google, which is a
 * transfer abroad the privacy policy does not mention — the same reasoning
 * that took Gmail out of the contact form's path in `worker/feedback.js`.
