 **One visual language, three modals.** `#appSettingsModal`, `#sessionOptionsModal` and `#createCaseModal` share the `set-*` surface (left rail, sections of grouped row cards, label + description on the left, control pinned right) through a single `:is(#appSettingsModal, #sessionOptionsModal, #createCaseModal)` scope in `styles.css`. An `:is()` list takes the specificity of its **most specific argument**, and all three arguments are ids, so every rule kept exactly the weight it had when the block was `#appSettingsModal`-only: nothing downstream shifted in the cascade. That property is what let the surface absorb Session Options and then Add Case in two separate commits without a cascade audit each time.
 
-Anatomy: `.set-shell` → `.set-shell-head` (title + `.set-head-actions`) + `.set-body` (grid of `.set-rail` and `.set-doc`). The rail holds `.set-search`, `.set-rail-items` and `.set-rail-foot`; the document holds `.set-section`s, each with `.set-section-head` + `.set-section-blurb` + `.set-group`s of `.set-row`s (`.set-row-text` = `.set-row-label` + `.set-row-desc`; controls sit in `.set-row-actions`). ⚠️ Close is deliberately **first in the DOM** inside `.set-head-actions` so the focus trap lands on it rather than on Save; `row-reverse` is what puts Save to its left visually on phones.

Apply (`applyAppSettings()`) sits beside Save in the same actions and saves without closing; it only sets a one-shot flag that `saveAppSettings()` consumes before its first await, so a Save clicked mid-Apply still closes the sheet.
 
 **The rail means two different things, and that is deliberate:**
