/**
 * Linen Theme - Pico CSS (Light + Dark)
 *
 * Restrained, warm-neutral theme with:
 * - Cream/parchment surfaces, near-black ink text (light) / warm-charcoal
 *   surfaces, near-white ink text (dark)
 * - Two type families only: IBM Plex Serif (body), IBM Plex Mono (labels/meta)
 * - Sage-green primary, terracotta secondary/danger, amber accent/warning --
 *   same roles in both modes, values swap via the custom properties below
 * - Dark variant: see the
 *   @media (prefers-color-scheme: dark) block at the end of this file for
 *   the palette and the reasoning behind each override.

/* Nothing here ever set a bare heading color, so h1-h6 fell through to Pico's own default
   heading color rule (which has its own, different, dark-mode value) --
   invisible in light mode because Pico's light default happens to be
   close to our --text-color by coincidence, but wrong in dark mode where
   the two diverge. Confirmed in-browser: before this rule, .home-hero h1
   rendered rgb(240,241,243) (Pico's own dark heading color) instead of
   this theme's rgb(242,240,236) (--text-color) under prefers-color-
   scheme: dark. Every page with a theme-set heading color (.home-hero h1
   etc) already overrides this by selector specificity, so it's additive,

   theme's --surface/--text-color/--border-color. Nothing here ever set
   these on the bare elements, so every plain form control fell through
   to Pico's own dark palette instead of linen's -- the same bug reported
   against Studies/focused/create-form.php's #topic-search. Confirmed
   in-browser before this rule: login's email input rendered

/* ===================================================================
   DARK THEME (auto) -- prefers-color-scheme
   Built from scratch -- linen had no dark variant before this (see the
   file header comment above, now stale as of this block).

   Root cause of the original defect: nothing pinned color-scheme or
   data-theme, so on a dark-mode device Pico auto-
   switched every BARE/unstyled element (headings, form inputs) to ITS
   OWN dark palette, while every element this theme actually styles
   stayed on linen's light-only colors -- illegible in both directions
   depending on the element.

   This block covers both halves of that: the :root custom-property
   overrides reach every rule already written against var(), which is
   the majority of the file (including the --text-muted/--text-muted-2/
   --brand-danger promotions made alongside this block, replacing what
   used to be literal hex on ~40 declarations). The explicit per-
   selector overrides below reach the remainder -- semantic state
   triads and a handful of one-off accents that don't route through a
   shared variable. `color-scheme: dark` on :root is the direct fix for
   a bare <input> picking up the browser's own near-black default -- it
   tells native form-control rendering to use
   dark-appropriate defaults instead of pure light-mode assumptions.
