/*
================================================================
TUTORIAL VIDEO: floating tab, footer access, dialog / bottom sheet.
Source of truth: Figma nyO6okhfumoV57zmCrkhR0, review board 2:2.
Desktop 1920/1440 dialog 7:309 / 7:500 (1088 × 880), tablet 1024
7:644 (944 × 820), mobile 424 sheet 7:166 (424 × 748), tabs 2:30
(56 × 216) and 2:40 (196 × 52), cover 7:457, footer access 8:125.

Scoped to .nios-tutorial*; colours are the theme tokens only.
Physical `left` on purpose: the tab hugs the LEFT edge in the RTL
site too (a logical inset would flip it), same reason as the cart
drawer and the footer's decorative images.
Breakpoints: the sitewide 768 / 1200 system. The vertical tab also
needs 560px of height; shorter (landscape phones) uses the
horizontal tab.
