The scoped reset `.pticaRoot button { font: inherit }` had specificity (0,1,1),
beating single-class button rules like .navItem (9px), .tab (11px), .detailBtn
(9px), .ptab — so every cockpit button was forced back to the root 13px. The
oversized labels overflowed the 96px left rail (icons/text shoved right of
centre, «неровное») and bloated tabs/buttons across the cockpit.
Wrap the selector in :where(button) → specificity (0,1,0); the per-component
classes (later in source) now win their font-size, matching the prototype's
bare `button {}`. Verified on a live local render: rail labels 13→9px and every
item re-centres at 47.5px; tabs 11px; detail buttons 9px.
