/* L-1 · 새 기본 틀 — Knowit Medi colours on the LAYOUT&MOTION system (DriveBerry-style layout and motion).
   Page states, set on <html> by l1-page.js (nothing here depends on the board template's classes):
     data-l1-mode="live"    real scrolling, wide (>= 900 px), scroll-driven animation supported, motion allowed:
                            the hero is a pinned runway (3D logo rises out, the phone comes up and moves aside).
     data-l1-mode="poster"  wide but not live (the canvas view, older browsers, reduced motion): every section
                            shows its finished composition, standing still.
     data-l1-mode="plain"   narrow screens: one column.
     data-l1-motion="on"    scroll-driven entrances and fills are allowed (any width).
     data-l1-flight="on"    the 3D logo flies (menu bar hidden until the main screen arrives, then the logo lands in it).
     data-l1-pin="off"      하는 일: a white card would not fit under the tabs in this window, so it scrolls with its row.
   With no attribute at all (script not running) the page reads as poster / plain by width. */
