+## Styling
+
+`style.css` is one global stylesheet (no scoped/component styles) with a
+handful of conventions worth knowing before adding to it:
+
+- **Tokens** (`:root` custom properties): colours (`--bg`, `--surface`,
+  `--border`, `--text`, `--muted`, `--accent`(-text), `--error`, `--warn-bg`/
+  `-border`), a border-radius scale (`--radius-sm` 6px compact controls,
+  `--radius-md` 8px buttons/inputs, `--radius-lg` 10px tiles, `--radius-xl`
+  12px panels, `--radius-pill`), and two opacity values (`--opacity-disabled`
+  0.6, `--opacity-ghost` 0.5 for a dragged item's placeholder). Reach for one
+  of these before hand-writing a value that's really just "the same grey
+  border again" or "the same rounding as every other button."
+- **`.field`** is the one themed `<input>`/`<textarea>`/`<select>` look, used
+  everywhere from the login form to the sidebar's project switcher.
+  `.field--compact` is the same thing smaller, for a control that's a flex
+  child beside a button (an inline "add" row) or squeezed into the sidebar.
+  `.field--autosize` adds the `resize:none; overflow:hidden` the dashboard's
+  JS-driven auto-growing textarea needs. Crucially, **`.field` is applied
+  directly to the control**, not to a wrapper (`.form input` no longer
+  exists) -- see the next point for why that's load-bearing, not just style.
+- **Put component classes on the control itself, not a wrapping element**,
+  for anything that needs a `:focus` state. `input:focus`/`textarea:focus`/
+  `select:focus` (global, removes the default outline and colours the border
+  with `--accent` instead) has specificity `(0,0,1,1)` -- one pseudo-class,
+  one element. A rule shaped `.wrapper input { border-color: var(--border) }`
+  ties it exactly, and being unconditional, silently wins that tie by simply
+  appearing later in the file -- the input keeps `var(--border)` forever,
+  focused or not, no matter what `:focus` says. `.field`, applied straight to
+  the element, is `(0,0,1,0)` -- strictly lower, so it can never win that
+  tie regardless of source order. (This bit a real shipped version of the
+  app: half the inputs had a working focus ring and half silently didn't,
+  purely from which pattern each one happened to use.) A component that
+  needs its own more elaborate `:focus` state (`.card-row__text`, background
+  swap included) writes `.card-row__text:focus` explicitly -- specificity
+  `(0,0,2,0)`, genuinely higher, wins outright rather than by luck of
+  ordering.
