Three things, all on the same surface.
**Tighter.** The shell drops to 760x620 (was 840x700) and the density comes
down with it: rail 176px, doc padding 15px, row padding 5px 10px, group gaps
3px, section head 0.88rem, row label 0.76rem, description 0.645rem. The model
cards were the biggest block in the document and shrink the most (6px 8px
padding, 0.72rem name). The toggle switches keep their size on purpose - only
the space around them was the problem.
**Checkboxes stay checkboxes.** The respawn cycle steps go back to real
checkboxes in a row card (`.set-checks` / `.set-check`) rather than the chips
they briefly became: they are numbered steps of one sequence, not a set of
independent tags, and chips read as the latter.
**Add Case joins the surface.** Same shell, rail and sections; its rail
switches panels like Session Options'. The six panels keep their legacy
`.form-row` markup - every id in them is read back by session-ui.js, so
restructuring the forms would be a lot of risk for no visual gain. Instead an
adapter block scoped to `#createCaseModal .set-doc` maps the old primitives
onto the look: a form row paints as a row card, its label as a row label, its
`.form-hint` as a row description, `<details class="advanced-options">` as a
collapsed group head. `.form-row` everywhere else is untouched.
With that, `.modal-tabs` / `.modal-tab-btn` / `.modal-tab-content` have no
users left, so their CSS is deleted from both stylesheets and the guard in
test/app-settings-structure.test.ts flips from "the settings modal must not
steal these shared classes" to "nothing uses them any more" - a reappearance
now means a modal drifted back off the shared surface.
Session Options was the last modal still wearing the old chrome: a strip of
top tabs over `.form-row` stacks, sitting next to a settings modal that had just
been rebuilt around a rail and grouped row cards. It now uses the same surface.
The `set-*` rules move from `#appSettingsModal` to
`:is(#appSettingsModal, #sessionOptionsModal)`. An `:is()` list takes the
specificity of its most specific argument, and both arguments are ids, so every
rule keeps exactly the weight it had - nothing downstream shifts in the cascade.
What the two modals do NOT share is what the rail means:
- App Settings stays a table of contents over one scrolling document.
- Session Options switches: one `.set-section` visible, `.hidden` on the rest.
Summary owns its own scroller and Respawn is long, so stacking them into a
single document would bury both. `switchOptionsTab` now queries
`.set-rail-item` (it read `.modal-tab-btn` before) and resets the document
scroll, so a switched-to section starts at its own top.
Phones get a horizontal, scrollable rail strip rather than App Settings' sticky
jump pill, which Session Options has no equivalent of. That is close to the tab
bar it replaces, so the phone gesture is unchanged.
Content is regrouped into the row language - label, description, control pinned
right - across all four sections: usage limits / respawn loop / cycle steps /
loop control, identity / token management / this session, tracker / limits, and
the summary timeline. The three cycle-step checkboxes became chips, which is why
`_syncSettingsChips` now covers both modals and Session Options registers one
delegated change listener per page for them.
Every id and handler the JS reads is preserved, and the component classes it
queries (`.duration-preset-btn`, `.duration-custom-input`, `.color-swatch`,
`.respawn-status-text`, `.run-summary-filters .filter-btn`) are untouched.
`data-claude-only` moved onto the rail entries, so external-CLI sessions still
lose Respawn and Ralph and land on Context.
`.modal-tabs`/`.modal-tab-btn`/`.modal-tab-content` now belong to
#createCaseModal alone. test/session-options-structure.test.ts pins the rail to
section pairing, the ids openSessionOptions reads, the one-visible-section
invariant and the Claude-only entries.
