   askunclejifu.com — MONO v2 ("subtraction")
   --------------------------------------------------------------------------
   Refinement of /css/mono.css?v=20261025 (mono v1). Same visual language:
   ink on paper, system fonts, zero radius, hairline rules, one restrained
   accent. What changes is DENSITY, not voice:
     - fewer surfaces, more air between them
     - body 18px / 1.65 (v1 was 18-21px / 1.5 with grey body text)
     - reading measure held near 68ch (v1 prose was 70ch, cards ~45ch)
     - ONE accent (#0b5c5c, already in v1's --tint), used on rules, links and
       links only. Never on headline text, never as a button fill.
     - motion cut to a single 140ms colour transition

   SAFETY CONTRACT (this site once shipped black-on-black through an
   injected style block). Therefore:
     1. NO :root custom property declarations at all. Tokens below are
        literals, repeated at use sites where needed.
     2. NO element-level `html{}` or `body{}` rules. All typography is set on
        `.auj` wrappers, so an injected <style> that colors body/root wins by
        cascade order and nothing here can repaint it black.
     3. Scoped selectors only. Nothing in this file matches a bare element.
   If you need a page-wide reset, do it in the consuming page, not here.
