/* PORTFOLIO — shared stylesheet
   Fonts are centralized as CSS variables below so swapping typefaces later
   only means editing this block — nothing else in the site's CSS
   references a font name directly.

   Font (20 October 2026): Helvetica Neue LT Pro from Marlene's Adobe Fonts
   web project https://use.typekit.net/jnq5aug.css, linked in the <head> of
   every page, so the site looks the same on every device (before, it used
   whatever Helvetica the device had: Helvetica Neue on Apple devices,
   Arial or Roboto elsewhere).
   Weights, as before: 500 (65 Medium) for the name, titles, menu, years and
   Back; 400 (Regular) for the text boxes; 700 (Bold) for "KOFFER17." and
   "GlogauAIR.". The web project holds all three (plus Condensed Bold,
   not used).
   Helvetica Neue and Arial below only show if Adobe Fonts can't load. */

   phone.js adds the class "rot" to <html> when a touch screen is held
   upright. The page is then drawn turned 90 degrees clockwise: it lies
   on its side and fills the screen, so visitors turn the phone. --lw and
   --lh are the page's own (sideways) width and height, set by phone.js. */
