/* ============================================================================
   bigcoat.co — stylesheet
   Implements Lynne's design spec (2026-06-27) + Joe's sign-off amendments:
   (1) Newsreader (not Fraunces) for titles & modal commentary;
   (2) 2-column grid on phones;
   (3) Brand accent = MUSTARD #E8B931 (matches the shared favicon set), not the
       spec's terracotta. Mustard is light, so the accent splits into a bright
       shade for fills and a dark shade (--accent-deep) for text/lines/focus on
       the light ground — see the token block for the AA reasoning.
   The quietest site in the family — the work is the only loud thing. The accent
   is structural ONLY (focus, active tag, for-sale mark, buy button). Warm paper
   ground, near-invisible chrome, print-not-UI imagery (no shadows, no rounded
   corners on images).
   ========================================================================== */

  /* Colour (§1.2) — near-monochrome warm; imagery brings all the colour. */

  /* Accent — mustard, the brand colour (matches the shared favicon set).
     STRUCTURAL ONLY (focus rings, active-tag fill, for-sale marker, buy button).
     Mustard is light, so the role splits by background to keep AA:
       --accent       bright mustard — for FILLS only; dark ink text sits on it.
                      #E8B931 on the paper ground is ~1.7:1, so it is NEVER used
                      as text or a thin line on the light ground.
       --accent-deep  dark mustard — for anything on the LIGHT ground: focus
                      rings, accent-as-text, the buy-button outline + label, the
                      active-thumb border. #8A5F06 on #FAF8F4 ≈ 5.3:1 (AA text).
     Text on the bright-mustard fills is --ink (≈9:1 on mustard), not white
     (#fff on mustard is only ~1.8:1). */
