   just a TV — "Bench Lamp"

   The look comes from one place: a neighbourhood electronics repair bench at
   night. A television opened up, its service sticker peeling, an anglepoise
   lamp, a printed service manual held open with a screwdriver.

   Collision: 1980s service manual meets serious newspaper editorial. Hairline
   rules and monospaced labels from the first; an editorial serif and long
   measure from the second.

   Deliberately NOT: a "hacking" site (black background, matrix green), a
   wellness app, or anything with a purple gradient.

   Palette "Bench Lamp", taken from that bench rather than from a swatch file:
     paper   manual stock, warm and slightly aged
     ink     printing ink on cheap paper — warm black, never blue-black
     board   the green of a bare printed circuit board, desaturated
     amber   the standby LED on the front of a set: off, but not really off
     rule    the hairline of a technical drawing
   =========================================================================== */

       Same bench, but with the lamp on. The greens and ambers are pushed up
       to where they read as colour rather than as tint, and a fourth accent
       joins them: the cyan glow of a screen that is actually switched on.
       That one is what stops the palette reading as sepia.                */
