feat(home): open-tab column on the desktop home screen; bigger phone home button
The welcome overlay centers ~560px of content in a ~1400px window, so both gutters are dead space. The left one now carries the open tabs as a vertical list (home-sessions.js): one row per live session plus saved web tabs, in TAB order rather than by urgency, because the row badges are the Alt+1..9 indices. Clicking a row enters that session. Working state is deliberately the phone's, exactly: a pulsing green dot ringed by the same tab-load-spin the tab strip uses while a tab loads, now with a green halo added on both surfaces so "working" reads identically wherever you see it. The column is position:absolute so the centered content never moves, which is why it needs a width gate in two places (HOME_SESSIONS_MIN_WIDTH = 1180 in JS, a max-width: 1179px media query as the backstop for a resize that outruns the matchMedia listener). A test pins the two equal. State classification is reused from mobile-overview.js rather than re-derived, so the two home screens cannot disagree about what counts as needing you. Phones keep the mobile overview, and their brand "C" was a 0.85rem inline span, roughly a 12x13px target on the one control that gets you back to that screen. It is now a 44px-wide button filling the full header height, with the glyph scaled to match. 44 is horizontal only: the phone header is pinned to 36px and clips overflow, so a true 44x44 would mean taking height off the terminal. Verified end to end against a real isolated instance (own tmux socket + data dir): 18 browser checks covering render, live update through the tab renderer, the working dot's animation/glow/ring, row click, the narrow-window gate, the phone fallback, and a real touch tap on the far corner of the new hit box.

/**
|
||||
* @fileoverview Desktop home screen session list: the open tabs as a vertical
|
||||
* column down the left of the welcome overlay.
|
||||
*
|
||||
* The welcome screen centers ~560px of content in a window that is usually
|
||||
* 1400px+, so the two gutters are dead space. The left one now carries the same
|
||||
* list a phone gets on its home screen (mobile-overview.js), turned vertical:
|
||||
* one row per live tab, in TAB ORDER (not sorted by state) so it reads as the
|
||||
* tab strip rotated, and so Alt+1..9 still matches what you see.
|
||||
*
|
||||
* DESKTOP ONLY, and only in a wide enough window: the column is absolutely
|
||||
* positioned so the centered welcome content never moves, which means it can
|
||||
* only exist where the gutter is genuinely wider than the column. Below
|
||||
* `HOME_SESSIONS_MIN_WIDTH` nothing renders; on a phone the mobile overview owns
|
||||
* the home screen entirely and this surface stays out of its way.
|
||||
*
|
||||
* The working state is deliberately identical to the phone's: a pulsing green
|
||||
* dot ringed by the spinner a tab shows while it loads (`tab-load-spin`, reused
|
||||
* from styles.css), plus a green halo. Same signal, same motion, both surfaces.
|
||||
*
|
||||
* Everything renders from state the page already holds (`this.sessions`,
|
||||
* `this.cases`, `this.pendingHooks`, `this.webviews`) — no endpoint, no SSE
|
||||
* event, no schema. State classification and case matching are reused from
|
||||
* mobile-overview.js rather than re-derived, so the two home screens can never
|
||||
* disagree about what "working" means.
