/* ============================================================
   DEVLOG (/devlog)
   ------------------------------------------------------------
   A log sheet clipped to the machine: a left rail of dates and
   a right column of entries, ruled off from each other by the
   same hairline the rest of the gate uses. Palette, type and
   spacing come from reset.css — this file adds no colours of
   its own beyond the four change tags, which have to be told
   apart at a glance and so borrow the semantic tokens.

   Loaded after auth.css and before touch.css/responsive.css,
   so its own breakpoints sit at the same widths as the gate's
   (900px = tablet and below, 600px = phone).
