/* [2026-09-21, SPEC 128 W7, D7] THE SHELL SHEET - HIDE THE NAVIGATION. A's reversal of R41, in his own words: "the press should put the whole navigation away, not shrink half of it." §118's press minified the 248px rail to 56px and R41 SPARED the CRM sub-column, the tab bar and the sub-bar by name; this round the same press hides all four. WHY THIS FILE EXISTS AT ALL, AND IT IS NOT A PREFERENCE. `srm.css` and `srm.js` are pinned to the character by ten exact-equality gates (829,969 / 253,445), so the state cannot be added by widening `body.is-navmin`'s selectors where they stand. A new sheet, linked between `_base.html:14` and `:15`, is the only way to override the shell from outside it without moving one byte of the two registers. `srm-shell.js` is its other half for the same reason. IT LOADS AFTER `srm.css` AND BEFORE `{% block page_styles %}`, which is what makes both halves of this file win and still leaves every page sheet above it: `--sidebar-w` is re-pointed at the same specificity srm.css:225 uses for `body.is-navmin` (0,1,1), so document order decides and this file is later; and `crm-incoming.css` can still re-express the Incoming page's own height band under the same state (`crm-incoming.css`, D20). DESKTOP ONLY (≥980), AND THE BREAKPOINT IS THE SHELL'S OWN. Below 980 the sidebar does not exist (`srm.css:183-186`) and the tab bar IS the navigation - hiding it would leave a reader on a phone with no way to anywhere. The press keeps its §118 behaviour there, which is visually inert, because `srm-shell.js` declines the event under 980 and lets `srm.js`'s S118a have it. THE BATCH BAR FOLLOWS WITH NO RULE OF ITS OWN. `.srm-batchbar` is `position: fixed` and a descendant of neither the aside nor `.srm-body`; it reads `--sidebar-w` for its grid pad (`srm.css:2553-2555`), so re-pointing that token to zero on takes its gutter with it and the bar lands on the main's own `--sp-6` edge. That is the same mechanism `body.is-navmin` uses, which is why the token is re-pointed here rather than the bar being named. */ @media (min-width: 980px) { body.is-navhidden { --sidebar-w: 0px; } /* ALL FOUR NAMED ONE BY ONE. A collapsed selector would let three of them fall out of a later edit silently - INBOX-RD-22's own lesson, one surface along, where the Focus block was re-aimed and the four selectors kept their own lines for exactly this reason. */ body.is-navhidden .srm-sidebar, body.is-navhidden .srm-subrail, body.is-navhidden .srm-tabbar, body.is-navhidden .srm-subbar { display: none; } }
